Project Osiris v1.0.1

Just made a quick bugfix update to sort out some slightly embarrassing bugs.

• Fixed DEFCVARs.txt so the game can run on non-Windows machines, by removing all platform specific CVARS.
• Fixed bugged elevators in MAP08 (I was tweaking texture alignments at the last minute, and forgot to raise them back up lol)
• Fixed 'fading' debug message during music fadeouts (again, last minute changes, oops)
