Fix #9097: Upper 16 bits of cargo base payment rate were discarded. (#9098)

NewGRF spec says that base payment rate is 32 bits, but it was loaded into a 16 bit variable. This value is loaded into Money variable after inflation is applied.

Change: track hover position on Online Players GUI

Especially if there are many players online, trying to chat with
the right one can be a visual challenge. This can be solved by
highlighting the row you are on. This visual cue is often enough
for humans to find the right row.

Add: admin menu for companies in multiplayer games

You can now easily do:
- a password reset (unlock)
- remove an empty company (reset company)

Feature: rework in-game Online Players GUI

The GUI now more clearly shows some basic information about the
server you joined, your client name (and the ability to change it),
and what players are in which company.

It also contains useful buttons to press to join companies, chat
with other people, and for admins to kick/ban people.

Additionally, renamed "advertised" to "visibility"; this has to
do with future additions, but also because it is more clear in
wording.

Add: [Network] Validate the client name when receiving one from the server

This so names from other clients are known valid in the client as well, instead allowing some compromised/bad server to potentially crash clients upon certain expectations.

Change: treat languages as finished, if translations are 75% completed.
Unfinished translations are not auto-picked from the locale.
In release builds, unfinished translations are not offered in the GUI.
Unfinished translations are available in non-release builds, or by editing openttd.cfg.

Codechange: Scale rating minigraphs on station window list. (#9075)

Minigraphs did not adjust size to accomodate large text, either by font size or font zoom, leading to cropped labels.
Minigraphs and spacing are now scaled by font zoom, as this seems to behave better than gui zoom in this instance.

Cleanup: Remove unnecessary parameter of GetScrolledRowFromWidget()

Line height defaults to the resize height of the relevant widget, which is
set in all cases. Therefore it is not necessary to specify this value every time.

Additionally fixes scrolled padding for the framerate window.

Cleanup: Replace single-use Pair struct with std::pair.

This struct is defined in geometry_type but not used by any geometry-related
code, only for subsidy code where both parameters are cast from int to
NewsReferenceType.

Doc: server name doesn't need to be advertised to be valid

Strictly seen the comment is true, as it says 'e.g.', but it is
misleading. The server name is just that: the name of the server
as configured. No need to mention advertising.

Codechange: remove always-empty "address" from NetworkContentSocketHandler

When ever you saw this debug lines (which you never should), they
showed an empty address. It is also not very useful to have, as it
always points to a known server anyway.

Codechange: split ParseConnectionString into two functions

One also looks for a company, the other doesn't. There were more
uses of the latter than the first, leaving very weird code all
over the place.

Remove: "language" field from server/client

The original idea was that people could find a server they could
talk in their native language on. This isn't really used in that
way. There are several reasons for removing this:

- the client also sends his "language" to the server, but nothing
is doing anything with this.
- flags are a bad way to represent languages, and over the years
we had several (rightfully) complaints about this.
- most servers have their language set to "All", and prefix the
servername with the language it is about. This is a much more
efficient way to do the same.

All in all, this feature should go back to the drawing board.
Maybe it could work in another form, but this form is not it.

Remove: "map_name" from server announcements / listing

The idea back in the days was nice, but it never resulted in
anything useful. Most servers either read "(loaded game)" or
"Random Map", neither being useful. It was meant for heightmaps,
so you could find a server that was using a specific one .. but
there are many things wrong with that idea. Mostly, servers tend
to save and load savegames from time to time, after which the
original heightmap used was lost.

All in all, removing map_name all together is just better.

Fix #9042: Make multiplayer server list height auto-fill window.

#9042 did not fix all combinations of scaling options. This additional
change makes the server list automatically fill available height.

Change: Improve layout and spacing of vehicle group widgets. (#9041)

Existing layout included a blank widget above the group list to align with the vehicle list, however since then an additional sort-by row was added.
Group list size tweaks to match normal row size (at least with normal gui and text size.)
Removed reduction of 2 rows in the group list <- main culprit of odd sizing.
Removed fill attribute on buttons which gave strange sizes, and put it on the group info widget instead.
Tweaked various soft-padding values to line up (centreing text with a 1px offset does not make centred text.)

Fix: Sizing of Multiplayer server list incorrect when GUI zoom doesn't match Font zoom.

The server information panel was scaled by GUI scale, which could result in a panel that is longer than the server list. This height difference is then maintained when the window is resized to fill the screen.
Instead, specify the minimum size by number of text lines and (summed total) padding.
