Fb, Twitter, and google oauth

Added artdarek library

Made facebook.js 

Made apiController

Added fb sign in button on sign in modal

Added fb like widget as test on how it works

Having problems with artdarek config. It disapeared and I had to try and recreate it.



Wish the comments were a bit more detailed. Not sure why a separated controller was created here? Is this just for organizational purposes? How are we calling these functions if they are not within a class?
