(svn r6876) -Codechange: Change the naming of _PLAYER in DESTTYPE_PLAYER/NETWORK_ACTION_CHAT_PLAYER
to _COMPANY as that is whom you are really addressing to. Also change some variable
names, 'desttype' is confusing if there is also a parameter 'dest', so rename it to
just type.

(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 r3077) static, const, bracing, indentation, 0 -> '\0'/NULL, typos in comments, excess empty lines, minor other changes
nothing spectacular, just some stuff, which piled up

(svn r3067) - Feature: allow unbanning players based on banlist-id (as well as IP).
- Feature: 'status' and 'clients' now show the IP of the players

(svn r2962) - const correctness for all Get* functions and most Draw* functions that don't change their pointer parameters
- change a lot of byte player types to PlayerID
- beautify header files, same "#endif /* filename */" ending

(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 r1320) -Fix: fixed chat-bug (that from a certain moment, nobody could talk).. 1
variable was still byte instead of uint16 (with a very big tnx to guru3!)

(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 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>'
