A bit more work getting content display in order

- content title added to the item shape (@Model.Title)
- some rough content item shape structure - needs real body zones and footer (need header @ footer markup at least as zone wrappers in a way so if there is nothing in the zone the tags aren't rendered)
- page title usage back in the picture though (impl.) not really touched
- contents and routable display type actions all falling back to the core shaped "Display" view
