MH2 Ambience Mute (ASI)

Install:   put MH2_AmbienceMute.asi in the Manhunt 2 folder (or its scripts\ folder, depending on your ASI loader).
           Needs a 32-bit ASI loader (e.g. Ultimate ASI Loader as dinput8.dll).
Uninstall: delete the .asi. No game files are modified.

How it works: when the game opens levels\<level>\resource2.glg, the ASI gives it a copy (in %TEMP%\MH2_AmbienceMute\)
with every AMBIENT_STREAM VOLUME set to 0. Music/SFX records are untouched.
