SDK Deletes Spatial When RigidBodyControl is Added

[john01dav]

Right-clicking on a spatial in the SceneCompoer deletes that spatial from the editor area and then from the actual file when saved. It does not, however, remove it from the SceneExplorer.

It also produces the following in the "Output - Application" area:

This appears to be caused by a missing bullet library of some sort.
