Allowteamchange fix
Fixes "allowteamchange no" to actually work properly and NOT desync you from the game in most cases. You can now switch TO spectator freely (as intended it turns out), and switching FROM spectator is prohibited. The "Enter Game" menu option in Match/Tag now displays one of those blue window notices just like with "Change Teams" in CTF/Team Match if you cannot change teams right now. Everything else works as you'd expect.
The de-sync issue was originally reported here https://mb.srb2.org/showthread.php?p=789965#85
See merge request !168
This is used by Command_Addfile in the MD5 calculation code, so that it can search subfolders properly and allow addfile in netgames to treat them the same way as in SP
* Fixing an inconsistency with being able to change skin colours when you shouldn't be able to, much like the previous skin change issue that was fixed.
-If the server tries to kick a joiner who is downloading the game state, they will get a timeout instead, because a regular kick would only happen once the game state has been downloaded
-Added a timeout for player ticcmd packets, again to prevent freezes to happen in some cases
-File/game state downloading is now faster, the speed is controlled by the "downloadspeed" cvar, in packets per tic
-The reason is now properly shown when the server refuses connection
-Changed the default values of "nettimeout" to 10 seconds (previously 15) and "maxsend" to 4 MB (previously 1)
-Added a "noticedownload" cvar that displays a message in the server console when someone is downloading a file
This fixes Brak's electric barrier disappearing for joiners to ERZC. There seems to be some issues with the lava falls there too I've found, but the electric barrier actually stays around now at least
P_RandomChance is now a macro for something that should happen a
certain percentage of time.
P_SignedRandom was moved to a macro. Nobody cared.

Use whatever names you want for your music. So long as you prefix the lumps with O_ or D_, it doesn't matter anymore.
DISCLAIMER: Linedef type 413 (change music) and Lua scripting is not tested.

Also makes comptime.bat work with git if able.
Development builds will now show the branch and the SHA1 hash of the revision. Also been tested to work with subversion, where it displays "Subversion r####". You know, just in case.
