- Added a compatibility option to fix Super Sonic Doom's first bonus
  stage leaving you frozen when you finished it.
- Always clear bEvilGrin after checking it in FMugShot::UpdateState(). If
  it's not an appropriate time to show the grin when the flag is set, it
  shouldn't be saved until later.
Merge branch 'maint'
- fixed: The new XDeath code forgot to move the assignment of the flags4 variable. Also renamed the variable to avoid conflicts.
