Created Unite 2014 Demo branch

This branch captures the changes we made to the Angry Bot demo for
Unite 2014, and will be used by developers who want to follow along
with the video we are about to publish showing our demo.
added cursor icons to Login & Register prefabs

the arrow icon was missing from the Login & Register prefabs
fixed bug with SkipLogin option

the demo was freezing because it was not reading in the SkipLogin
option correct. Also the SkipLogin option was not persisting correctly,
and was not actually skipping past the login dialog.
