d57ba6a57b - Automatically reset fs_game to "" if it was supplied by the user and is equal to com_basegame

dee3724a13 - Improve game_restart: 
* differing screen resolutions and network settings are now honoured when changing fs_game
  * Fix hunk memory leak on game_restart
  * Move cls.state and cls.servername to clc so connection state is fully preserved over game_restart
  * Revert back to previous fs_game after disconnecting from a server that triggered a game_restart
  * Fix error dialog popping up after every game_restart if an error happened previously (reported by Ensiform)
- Fixed that not all commands added by CL_Init() would be removed by CL_Shutdown()

af5020c57c - Don't try to load QVM/DLL files on pure servers

9219cde4e8 - Small change to search path order - local files not in .pk3s take precedence over files in pk3s. Should make life easier for modders/mappers wanting to override textures that are already contained in some older pk3 
- Make VM loading more robust, change loading order: when vm_* == 0 first try loading DLL, then QVM in *each* search directory/path
- Fix FS_FileForHandle that would return a FILE pointer to invalid file handle 0

4b1418c4ad - Implement opStack protection: Use register %ebx for scaled indexed addressing mode to access opStack, make opStack push/pop operate on %bl portion only 
- Add a third pass to VM compilation for computation of jump address offsets, removing the need to dereference into vm->instructionPointers[] for every call/jump
- Make use of 0F opcode prefix relative jumps
- Call Com_Memcpy for OP_BLOCK_COPY
