Armature related fixes and cleanups:

* Armatures that had constraint targets inside other armatures
  weren't transform()-ing correctly

* Issues with lattice deformed objects that are parents of bones
  when rendering an animation. Seems to be mostly OK now with the
  exception of the first rendered frame -- weird bugs like this have
  plagued blender for ages, which leads me to believe that
  RE_rotateBlenderScene() is a piece of garbage that nobody understands
  (especially me).

* made a few helper functions to clean up some repeated code related
  to clearing constraint status and rebuilding displists.
