-	Identity.Entity.InMemory moved to a test project (Identity.Entity.InMemory.Test)
-	Identity.InMemory which was the identity in memory implementation also moved to a test project (Identity.InMemory.Test)
-	IClaimsFactory was promoted to a top level service and now adds any claims found in a Role that a user belongs to.
-	EF implementation now supports logins, claims, roles, two factor, lockouts
-	Initial pass at style cop (mostly line endings since resharper no worky :()
We should probably have a bug or a TODO tracking rationalizing these constructors when EF does, e.g. this should probably take a IOptionsSetup<DbContextOptions> instead of DbContextOptions directly.
