Social forks

@nockertsb here ya go.

Contains an updated version of the Facebook SDK. Been changed to target latest API and to use normal Fragments instead of support fragments. Also contains an updated version of the AndroidSocialNetworks library to use our local Facebook SDK and to use normal fragments instead of support fragments.

None of the APIs changed so you should be able to just drop this dependency in for the other one. `compile project(":AndroidSocialNetworks")` is going to be the new dependency.
