Pro ASP.Net MVC 5 Platform - Ch 13 - Continuing the Setup

Continued setting up the foundation. Created the user manager and made an
Owin config in a non-standard way - by putting an IdentityConfig class in
App_Start, setting the namespace to just Users, and setting the web.config
appSetting "owin:AppStartup" to "Users.IdentityConfig" (from the last checkin).
