Changes from QMM v2.0.0:
- added support for Quake 2, Quake 2 Remastered, and Soldier of Fortune 2 multiplayer
- cleaned up legacy plugin API variables
- allow plugins to get the original return value of a call (or the QMM_OVERRIDE/QMM_SUPERCEDE return value) in the _Post handlers with QMM_GET_RETURN macro
- plugin pifv bumped to 3:0
- added G_FS_FOPEN_FILE/G_FS_READ/G_FS_WRITE/G_FS_FCLOSE_FILE functionality (using FILE*/fopen/etc) for plugins/QMM to use for QUAKE2, Q2R, and MOHAA
