RootMotionComponent

The component the root motion is relative to. This was found to be needed since, in our examples, we author root motion anims where Y is forward and we rotate the mesh components at the actor level so that X is forward. We need to know which component to rotate the root motion animation relative to. If we continue with this, this means all non anim based root motions should expect to follow the same convention. Need clarity here from animation team.
