Add Group Info and Group Journal page for Editor's Area

* Group Info (default editors area page) presents the user's group memberships
* Two new tabs: Your Group's Journals and Your Group's Applications (only the former currently works)
* Facetview mirroring admin page journal searches on Your Group's Journals
* Back-end changes to filter editor view of journals to only those journals for groups they are in
Create logical separation between the admin area's journal edit link and the actual handling of journal edits

The purpose of this is so that we can then re-purpose journal editing within the editor's area, and maintain separate role-based authorisations on the two routes to the edit form
Initial customisations to allow Editors to access the journal form

* Security framework for editors when accessing journal form
* Ability to route Editors to journal edit handler
Allow Journal edit form to be accessed via the editor area and support the assigment of associate editors to tasks

* Continues the logical separation of journal handling code from web ui routes /editor and /admin
* customised permissions for different access routes
* changes to form template for editor route, to only give editors features they are allowed to hvae
* resolve the slightly fiddly workflow between admin assigning editor groups and editors assiging associates through the same form fields
