Starting to get a UI around content type management

- added a DisplayName to the ContentTypeDefinition
- added a CreateRouteValues rvd to go along with the existing display and edit
- set default display, edit and create route values for ContentItemMetadata (* should get fallback route values in a different manner. probably not good to refer to an area, even by string, in core from the fwk)
- starting to shape up the content type list into a more consistent UI
- added create type action, view, etc. for creating new content types
 - supporting service has a few default parts hard-coded for now
