GRIM: Rename Actor::Chore to Actor::ActionChore
EMI: Hide subtitle when stopping movie playback
EMI: Display subtitles with TinyGL

In EMI the screen is dimmed while playing movies. The blit() function in
TinyGL is required to work in that case so that movie subtitles are
displayed.
EMI: Fixed interpolation between animations and cleaned up the related code.
EMI: Implement keys for the animation component.

Key 3 seems to control whether the animation loops or not. If key 3 is not
set, the animation plays once and then deactivates. If the key is set, the
animation will repeat until the chore is stopped.
EMI: Allow StopChore without fade time parameter.
GRIM: Fix typo in GrimPatchesDesc.txt
