cordova: initial bindings for clay-mobile->cordova (native)

Also added Environment detection (kik/native/browser)
And when we add Twitter into the mix? And Facebook? 

What's better: 
1) send to native
2) fallback, try kik
3) fallback, check if being played in facebook webview
4) nope, post to twitter

or 
1) check if being played in facebook webview
2) nope, post to twitter

1) check if being played in native
2) yep, post to native
