Need to handle the case of the user not being connected to the Internet

[sean-shelton]

Right now, if the user isn't connected to the Internet, but they're logged into Facebook, it'll try to make a GraphRequest. This request will return a null pointer exception because it tries to make the request even if not connected to the internet.

I suggest that we surround this with a try-catch that doesn't make the request, and simply stays at the main menu.
