* Renamed BinaryClassLoader to SavableClassFinder and put it into core
* SavableClassFinder now can remap class names, it is used to load old J3O files with particles in them by remapping the old shape names to the new names.
* Moved the particle emitter control into an inner class so nobody fools around with it
* Loading of old particle emitters now works
* Fixed issue with input not responding
* Fixed some small javadoc mistakes in RenderState
* Javadocs for com.jme3.material (not done)
* AbstractControl will now throw exception when an already-attached control is added to another spatial
* All tests should now use non-deprecated ParticleEmitter.setGravity method
