Don't change RNG in demos incase they are static
Make sure use_staticrng is false if not needed

fixed some issues with reviving monsters

- fixed: Thing_Raise didn't properly set the spawn health.
- fixed: Thing_Raise did not the CanRaise state flag.
- fixed: Reviving a monster must also reset the damage type.
- fixed: Thing_Raise reset the actor after calling the raise state, but it should be before, just as the Archvile code is doing.
- consolidated some common code of Thing_Raise and Archvile resurrection into AActor methods.
Stop NetUpdate from corrupting demo playback
- removed redundant variable.
- typo in resurrection code.
made some changes to turn the CF_INTERPVIEW flag when changing angles into an op-in feature instead of making it automatic.
Merge branch 'interpview_optin'
- added new ChangeActorAngle/ChangeActorPitch ACS functions because the new required 'interpolate' parameter cannot be added to the existing SetActorAngle/SetActorPitch functions without breaking old scripts.
- removed the __asm nop breakpoints for debugging. They not only do not work on non-MSVC but also not on 64 bit.

- fixed: memory allocation for file names in 7z archives was broken. Changing it to use TArray instead of alloca makes it work.
