Created a generic login functionality that will work for all of the games. Made it customizable so that developers with actual artistic vision will be able to customize it as they care to by simply replacing some of the images.
The rest of the functionality is automagic - provide your information and so long as you have an AccountFactory, you will be able to have users log into the blockchain and return the useful bits. 

No, I'm not creating STEAM, Google, or Facebook's "hive" of user accounts. Own your own shit!
