Develop the content view user interface for the new hybrid U.I.
This include:

• the main View tab
• the details tab
• the versions tab
• the locations tab
• the "related content" tab

with similar behavior as in 1.x but based on the U.I. guidelines

Tech stuff

• A possible implementation approach is described in EZP-27449.
• At the moment, location view uses a template configured in views.yml. A custom controller can be added in the same place if needed (not a big if, as it will be needed).
