#968: private content must not be visible to all members of groups/communities

when a community/group has an intranet, only administrators (and moderators) must be able to see it's contents.

To implement this, we'll probably need to add another permission called "view_private_content" or something like that and assign this permission by default to administrator (and moderators).

probably we'll need to change the roles in the database to include the new permission
