Fixed issue updating the button caption after logging in or out
Renamed LoginView to LoginButton and added some "facebook" styling, rounded corners, luminosity effects. Also, moved common files from Facebook.Client-WindowsStore/Controls to Facebook.Client/Controls so that they can be shared by the WP8 project
Started porting the LoginButton control to WP8, updated sample app to show button
Removed binding to Label property in the LoginButton control template. This property is no longer supported.
Update LoginButton style, added gradient, updated visual state animations. Also, added code to retrieve button caption from localizable resources (still needs work)
