gmod_game: Use sv_tags to automatically mark TTT servers with..

Revision 910
Use sv_tags to automatically mark TTT servers with custom weapons (tag = ttt:custom_weapons) instead of adding asterisk to game description.
Locational voicechat now disabled when round is not active, fixes issues with talking to spectators after a round when loc voice was on.
Language files now load from GM.FolderName, no longer hardcoded.
Fixed rare error when receiving a radiocommand from an invalid entity (somehow).
