(svn r7505) -Feature: show NewGRFs used on a game server, show which NewGRFs you do and do not have.
-Feature: show NewGRF compatability of network games in the Game List window; a green square if you got the same OpenTTD version and have the needed NewGRF, a red square if the version does not match and a yellow square if the version matches, but the client is missing at least one of the NewGRFs.

(svn r7076) -Codechange: Prefer includes instead of using extern. Move UpdateNetworkGameWindow
declaration to network.h, and remove stale externs of NetworkPopulateCompanyInfo

(svn r6816) -Codechange: Some coding style, variable localization, const correctness.
-Codechange: 'quited' is not a word, use has_quit instead for NetworkClientState

(svn r6754) -Codechange: Remove some #idef ENABLE_NETWORK specific defines. With networking
disabled hardcode _networking/_network_available to zero and let the compiler
handle all optimizations.

(svn r6753) -Codechange: Move some function declerations from functions.h into network.h
and let NetworkDisconnect handle all shutdown related operations.

(svn r5999) -Feature: change the original date format to a 32 bits format based at the year 0.
The game date subsystem now allows someone to start in the year 0 and continue
up to the year 5 000 000. However, you currently cannot build anything before
1920 as there is no newgrf support for dates before 1920 or after 2090 yet.

(svn r5926) -Codechange: make _cur_year contain the full year, instead of the offset since 1920
-Codechange: store all year related variables that are _not_ stored in a savegame/transported over the network in the same format as _cur_year

(svn r5293) -Fix: Not all network interfaces are capable of broadcasting. Don't record those which aren't
-Fix: Not all networks are /24. Generate proper broadcast addresses for non-/24 nets

(svn r3409) - Change the server advertisement interval to use the frame counter instead
of game days. This allows a paused server to continue to advertise itself.
This also fixes advertising for games that start before 1922.

(svn r2581) Fix: Behave a bit safer if central server sends bogus information about clients.
Change: Made code a little bit more readable by putting _selected_item in a local var with a shorter name.

(svn r2308) - Fix: enforce server-only and/or offline commands by giving them flags in the process table. This also fixes bug "[ 1190944 ] Many commands not checked for security"
- CodeChange: move ValParamRailtype() to check rail type from command.h to vehicle.h where it is better suited.

(svn r2243) -Fix: Rework of console. Use 'help command|variable' to get help about it. You can assign variables with =, ++, --, or just new value. Console parser is now lenient towards typed spaces, and more robust in general (at least readable). Removed the 'set' command, instead implemented all such variables as 'variables'.
- Some variables are really special and cannot be assigned normally, use their callback procedure for assignment/querying. This commit also obsoletes "[1172804] Console set command cleanup"

(svn r2106) -Fix: improved the network-join algoritm, it is now a bit more stable
-Add: added 'pause_on_join' and 'max_join_time' for MP games, where you
can auto-pause the game when a client wants to join the game. This to
avoid connection losses because of big maps (200+ trains). (with tnx to
#openttdcoop for the ideas and testing)

(svn r1945) - CodeChange: re-commit of rev 1835: "Reduce the visibility of network_core.h (Tron)".
- VS6/.NET: moved ENABLE_NETWORK to the project file setting (same place as WITH_SDL, WITH_ZLIB) and removed it from network_core.h

(svn r1845) - Revert r1835 since it totally screws network compiling
- Fix: fix some VS.NET warnings
- Add missing file to VS.NET project file

(svn r1527) -Add: RCon (Remote Connection). A server can set:
'set rcon_pw <password>'
Which enables rcon. A client can now do:
'rcon <password> "<command>"'
The command will be executed on the server. (guru3)
-Fix: 'kick 1' did crash dedicated servers
-Fix: server password is now correctly saved

!!Warning!!: do not give your rcon password to people you do not thrust!

(svn r1510) -Add: Improved Network Lobby GUI: (bociusz)
- Added green dot if company income is positive (else red dot)
- Added lock icon if company is password protected

(svn r1322) -Add: banning system (mostly tnx to guru3)
A server can ban people via ClientList
Both server and dedicated can do it via console:
'ban', 'unban', 'banlist'.

(svn r1263) -Fix: [Network] Client-names are limited (serverside) to 25 chars
-Fix: You can enter some more chars in the chatbox

(svn r1252) -Add: [Network] With 'set restart_game_date' you can set the date for in
which year the server must restart hisself. (0 = disabled, default value)

(svn r1240) -Fix: OpenTTD once again compiles if ENABLE_NETWORK is disabled.
-Fix: removed some warnings
-Enabled ENABLE_NETWORK on windows again which I accidentally commented out.

(svn r1239) -Feature: Added gui option of setting company password. It can be found in the 'company information' window
-Spiced up 'set company_pw' a bit, where if no pw is typed, it shows the current one.
-Added a space between company name and player; looks better

(svn r1227) -Add: Ingame Server-list (select Internet, then Find Servers)
-Fix: UDPListener was launched wrongly
-Fix: Not all sockets have broadcast enabled anymore
-Fix: Server-advertise retries 3 times before giving up

(svn r1168) -Cleanup: [Network] Cleaned the network code a bit. Added 'const'
and 'void' where needed, prefixed all functions, typedefs and global
vars with 'Network' and organized all externals nicely.

(svn r1131) -Add: [Network] Autoclean_companies (set it with 'set autoclean_companies on/off').
When enabled, empty companies (companies with no active clients) with no
password are declared bankrupt after 1 year of emptyness.
For empty companies with password, the password is removed after 3 years
of emptyness.
The delay of removing company/password can be configured via:
- 'set autoclean_protected <months>'
- 'set autoclean_unprotected <months>'

(svn r1108) -Fix: [Network] Fixed problem around slow clients:
They joined, they got the map, but it took some time before the new
player was created. In this time a player could do stuff, causing a
player-id-mismatch, and the player was kicked out. Now a player get's a
nice GUI which says: registering.. When that is gone, the player is
joined and can play safely. Tnx to Moriarty for bugging me with this bug ;)

(svn r1106) -Add: [Network] Added master-server protocol and advertise to
master-server option. No GUI yet, and disabled by default (it still is WIP)

(svn r1096) -Fix: [Network] PlayAs is now registered correctly
-Codewise: [Network] Cleaned some code, removed some comment, changed
some wrong comment

(svn r1059) -Fix: [Console] Renamed 'set port' to 'set server_port'
-Add: [Network] Add ip-bind ('set server_bind_ip <ip>' in console or use
scripts/pre_dedicated.scr)

(svn r1057) -Add: [Network] 'set port <port>' changes the port of the server (after reboot)
-Fix: [Network] Fixed warnings that came with last revision
-Cleanup: [Network] Removed an unused var (_network_client_port)

(svn r1054) -Fix: [Network] Redid revision 1024, only a bit more nice this time
(revision length is back to 10, and checking is now done correctly)

(svn r1026) -Add: [Network] Added unique id, so in network, each client has an
unique id (generated via md5)

(svn r1024) -Fix: [New Network] Revisions can now be longer then 10 chars, so I made
it 20 chars long

(svn r240) -Fix: desync on subsidy generation
-Fix: sometimes commands got executed to early on some clients
-Feature: universal event packets for transmitting subsidys

(svn r229) -Fix: Some more const stuff fixed .(Tron)
-Fix: ParseConnectionString() function to parse network connection string: <IP>[:<PORT>][#<PLAY_AS] .

(svn r212) -Fix: Network-gui fixes (sign_de)
-Fix: any disabled button in a window doesn't receive WE_CLICK events
-Added network.h
