Registry: Rewrite as new "enhancer" object.

This means we no longer need to hook to pagecreate to do any enhancement. The page widget AMD-depends on the registry and calls $.mobile.enhancer.enhance( this.element[ 0 ] ) during its _create method. Since the widget factory triggers "pagecreate" after _create() returns, this also means that all registered widgets will have finished enhancing by the time pagecreate is triggered. This, in turn, means that implementors of third party widgets need no longer necessarily have to wait for pageinit. They can act on pagecreate.
Registry: Convert to private object instance.
Registry: Remove commented-out debugging code.
Widget factory: Add accessor definition function.
Widget factory: Move selector defintion into "expensive" section.
Widget factory: Do not assign the constructor to the namespace initially.
