Port Alien Frontiers to Android

[Clint Herron]

Note: Look more into using StellaSDK for this: http://www.cocos2d-iphone.org/archives/2013

Alien Frontiers uses Cocos2D and Objective C exclusively, with very little in the way of Apple visual components (exceptions being the WebView component for instruction manual, and the TextView component for the game log). Everything else is done in Cocos2D, so porting with Stella should (in _theory_) -- if not easy -- at least be straight-forward.

In theory.
