Fix some typos in Social API
In the properties file if we have

property = value

and the value started with an = sign then it would fail.  Fixed so that the token looks for any character.
Adding in the spaceship sample complete with scoreloop integration.  There are still a couple of bugs in the challenge code that need to be resolved with the scoreloop team.  It is currently set with the default UI.

Also adding in the Google Games code.  Need to complete the JNI calls and get it integrating with the library.
