Bug fixes, FlxGame, commented out _mouse.getFirstAlive...apps will crash if mouse is not used. Moved tg eventlisteners for onFocusLost and onFocus outside FlxG.mobile statement, otherwise the resume and pause won't be called on Android.
GdxGraphics and GdxStage, there is no way to check whether a disposable is disposed. Surrounded it with try-catch. Demos were crashing when running other demo.
