- Themes: Theme discovery and related infrastructure work. Theme content item and metadata (Theme.txt). Some initial Theme Admin and a couple skeleton themes.

- Extensions: Theme and Package extensions are now automatically discovered, their metadata parsed and their types loaded by the ExtensionManager. The ExtensionDescriptor now contains an ExtensionType property which will help distinguish extension types.
