Sphero control working on Android

##### Super Simple Sphero Sensor Bridge
* I added a __VERY__ basic implementation of a bridge between Java and C++ for passing necessary information down to cocos2d-x. The code can be easily modified to do other things. 

* I also changed the add order of the views so that the SpheroConnectionView would be visible on startup.

_Note: I only got this working in the most basic way. I would expect that a little cleanup is necessary. I hope this helps._
