Animation support for Qt3D

Modded assimp loader to load animations and to load submeshes into child
entities. Added keyframeanimation for node animations and morphing mesh.
Also added animation group for controlling multiple nodes as one animation
and animation controller to select and play animations.

Assimp loader adds QKeyFrameAnimations targeting an entity as child
objects of that entity, the QAnimationController finds them when the entity
is set and creates QAnimationGroups from based on the animation name.
