Added a preliminary android build environment file with some basic instructions. This is for Mac OS, easily modifiable for Linux but I wouldn't know where to begin getting this to run on Windows.

As this is no longer google specific, renamed everything google to qgc.

And name the target as the main app is now in its own sub project file.
