- Reverted updaterevision.vcproj to r385 and added a note as a build event

explaining the need to use mt.exe 6.0 or newer. Here is the note:
  VERY IMPORTANT: You must copy the mt.exe from %VSINSTALLDIR%\Common7\Tools\bin
  on top of the version in %VSINSTALLDIR%\VC\bin or your computer may restart
  while building.
- Changed the ASecretTrigger::Activate() fix: There's no reason open scripts
  shouldn't be able to activate secret triggers; players just won't get
  credit for it in coop.
- Added a NULL actor check to R_SetupFrame().
- Fixed: The player sounds in DEHSUPP were defined incorrectly.
