Fix incorrectly named MeshComponent
Removed ExampleComponent (it will now be in ExampleGame)
Added a dummy function so downstream libraries can force shared library to be loaded by depending on a symbol, even if they have no other explicit references
New data files to load in a complete scene with TestBull, already with components attached
Added dummy function to allow downstream libraries to force the linking of this shared library
- Fixed several bugs (null pointer dereferences) in asset loading when failing to load objects
 - Added PopulateStructure() functions for several asset types
- Bringing back ExampleGame with new example asset/component (it now runs, but doesn't do anything useful)
 - TestApp now loads a scene from file that includes a testbull rather than being setup programmatically
 - Bumping submodule references
