All these files were almost identical, so there is no good reason to
have them twice..
and change CMakeLists.txt accordingly
(Not that this commit won't compile because some #includes are still
broken - will be fixed in the next one)
And suddenly hosting a server on linux works at least locally
(with client and server on the same machine).
Even though there are still strange bugs (massive lags in one
direction, doesn't work in LAN), at least it works at all now.
D3BFG gets the username from Steam, in the GPL release it just
uses the hostname.
Now it's possible to set a custom name with the ui_name CVAR
(like in classic doom3). If ui_name is empty ("") the hostname
is used.
The window losing focus in MP resulted in the console being spammed
with "changing com_pause not allowed in Multi Player" (or similar)
messages. Added CVAR_NOCHEAT flag to com_pause to get rid of that.
It now works on Linux so executing it doesn't freeze the game
like described in
https://github.com/RobertBeckebans/RBDOOM-3-BFG/issues/33
Furthermore, this function doesn't have any parameters anymore
(on any platform) because the only thing supplied was the original
program arguments +"+set com_skipIntroVideos 1" anyway - this is now
done in Sys_ReLaunch() (also on Windows).
Having the program arguments as one string is bad on Linux/POSIX
because there it's expected that the program arguments are one
C-string per argument.
If the window loses focus com_pause is set to 1, when it regains focus
it's set to 0.
The behaviour on Win32 stayed the same (the implementation is less
hacky though) and Linux now matchces that.
