I broke the rock
Fixed the rotating rock by changing the offset of the cached image.
'GameEntity' created. Caching images for Drawables. Nothing really works, but I can at least put stuff onto the canvas using the new framework.
Adding callbacks to loading images
Rotating main asteroid finished with no clicking.
Broken; trying to fix having the wrong scope for the onLoadedImage callbacks.
To Alex: why is 'this' disappearing?
Clicking works. Removed Clickable. Added onClick listener to Drawable.
Dynamically adding new Rocks and Drones implemented. Clicking to gain money broken/not yet reimplemented.
Feature parity reached with trunk at branch point.
Split up framework files into reasonable places.
Remove duplicate code from the fat file.
Randomize drone velocity.
Merge branch 'oliverdoaner/rotate-rock'
