added an interface for making things that rotate via revolutejoints, and added a demo to show how to use it
updated getFont to work with new libGDX font interface
removed erroneous newline
renamed the Renderable interface to Lol.Renderable; also began transition from polling-based touch to GestureListener
another step toward gesture support
reformatting, and more work on the gesturelistener interface
Splash now uses gestures... this was easy, since there is only TAP, but it's a start...
minor cleanup
went back to extending Game, instead of implementing ApplicationListener manually
added comments
switched Chooser to gestures
HelpLevel now uses gestures, and also cleaned up gesture handling for all three gesture-based screens
Started converting Level to Gestures, by cleaning up a few other aspects of the code
