Create CompositeAppState.java

[scenemax3d]

For complex game state management, JME users can benefit from having a composite app state which handles child app states. This way the developer can easily organize his game states.

This composite app state is a contribution of Paul Speed and was copied as-is from:
src/main/java/com/simsilica/state/CompositeAppState.java

Hi @pspeed42,
Can you please review the license text and add whatever needed credit / reference to your SiO2 lib

Thanks again :)

To cover all bases, it might be nice to add a line like:
"Copied with Paul Speed's permission from: https://github.com/Simsilica/SiO2"
...somewhere near the copyright (maybe right before the all rights reserved).
It makes the pedigree clear and the permission explicit.
But it's technically fine as-is.
