Demo Update et al

First off, we have our second AGE-based game on Google Play! This is a puzzle/strategy genre. You can see it here.

Now that we have two complete games built with AGE, it's time to go back and update the demo!

Changes are small; the auto-rotating camera is gone. Now you move the camera via UI gestures: pinch to zoom and fling to rotate the camera position. The camera rotation isn't perfect, but good enough to demonstrate how to respond to UI events.

After posting new demo files, we will post another AGE release to the Files section.
