Browsing Collections / My Collections / Shared

New menu entry "Collections" giving access through 2 tabs to:

• "Shared": list of all the collections user has at least read permission on but the ones Private.
• "Private": the personal collections of the connected user (all but "My Favorites") where only the current user has right on it.

If there is no private or shared collections, display an "empty message".

• Ordered by last “new member added” date
• For each collection, display:
• the path where the collection is stored (using the breadcrumb enricher)
• the information about last modification (date and user)
