Fix for animation resources

The problem was that the invokeMethod between the AnimationReader thread
and the main thread was failing, because FBXGeometry* wasn't a registered meta type.

So, I ended up normalizing the AnimationReader class to be more like GeometryReader,
in that it uses singles and slots to communicate success and failure, rather then
invokeMethod.
