53d89b6c10 More color fixes for railgun
Show other players' railgun color and their firetime state.
Show snapshot client's color on world item models of railgun.
Fix the impact mark using color2 (spiral) rather than color1 (beam).
Credits go to Ensiform and Harekiet for the refire portion.

d57ba6a57b - Automatically reset fs_game to "" if it was supplied by the user and is equal to com_basegame
- Fix problem where users could change values of CVAR_INIT variables after the call to Cvar_Get() via Com_StartupVariable()
- Move sound shutdown after client shutdown so VMs don't hold invalid sound handles in memory

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
- Fallback after failed DLL load will be VMI_COMPILED, not INTERPRETED

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

03201aff22 - Add MASM assembler files for MSVC x64 projects to support vm_x86 in x64 mode
- Clean up ftol()/snapvector() mess
- Make use of SSE instructions for ftol()/snapvector() if available
- move ftol/snapvector pure assembler to inline assembler, this will add x86_64 and improve support for different calling conventions
- Set FPU control word at program startup to get consistent behaviour on all platforms

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
- Fix several missing range checks for vm->dataBase memory access

e08299faf4 - Do assignment of value 0xDEADBEEF after the 4-byte alignment

- Add support for "addb", "subb" etc. assembler mnemonic
- Change opStack protection for x86_64 VM: No overflow checks necessary anymore as offset register is 1 byte long only
