make internal diffuse apply to bmt attributes

diffuse from BitmapText attributes were not receiving internal diffuse
from their parent ActorFrames. This change waits until after the draw
cycle to reset the internal diffuse and glow, so any color applications
separate from generic diffuse can use the internal diffuse when desired.
Fixed CreateMethodTable to create a new table even when something of that name exists, so that the previously existing one that might have been modified by a theme is removed when changing themes.
Changed LifeMeterTime to not crash when not in course mode.  Changed _fallback's life settings back to forcing together.  Added ForceImmediateFailForBattery theme metric.  Gave up on FailFadeRemovePlayer lua function and removed it.
Change Windows installer to use the root drive, instead of a hardcoded C:\
