Support registration with named scope

[JoeRobich]

1) Scope names are a String. 2) Default scope name is an empty string 3) If you resolve without specifying a scope, and there is a default scoped registration, it is returned. 4) If you resolve without specifying a scope, but you only have scoped registrations, any one of them will be returned. 5) If you attempt to resolve for a specific scope that has not been registered, an error is thrown. 6) Scope will be passed into registration callbacks i.e. function(factory:AsFactory, scopeName:String):Object 7) Property injection resolves property types with same scope name as type resolution

Fluent interface now fully supports named scope my using the inScope and fromScope methods.
