BGE: Cleaning up BL_ArmatureObject so it has direct control over its armature and pose. It now also copies armatures to avoid needing to swap poses around. This makes updating pose data more thread safe.
BGE: Using OpenMP to thread the pose updates. Helgrind still reports some errors that need to be fixed.
BGE: Removing unused code from BL_ArmatureObject and renaming BL_ArmatureObject::SetActiveAction() to UpdateTimestep().
BGE: Allowing the BL_SkinDeformer to be updated in a loop in KX_Scene::UpdateAnimations(). OpenMP is then used to thread that loop.
BGE: Moving mesh copy code from BL_SkinDeformer::Apply() to BL_SkinDeformer::UpdateInternal() so the code can be run in parallel.
BGE Cleanup: Replacing a switch in BL_SkinDeformer::UpdateInternal() with a simple if/else.
BGE: Have the BL_Action keep a copy of the action it needs to use to avoid threading problems.
BGE: Combining the two threaded loops now that helgrind no longer reports errors for either of them. This gives a slight performance boost.
