Log Message:
-----------
Fix for bug #4192: game engine armatures that are dynamically added
but don't have an action got the pose of already added armatures, even
though they're not related. This also fixes an issue where the armature
in Blender would end up in the pose from the game after ESC, removes
unneeded copies made during armature evaluation, and also solves the
constraint copying hack.
