Noah Petherbridge eb85b2e090 Forum Memberships & My List
* Add "Browse" tab to the forums to view them all.
  * Text search
  * Show all, official, community, or "My List" forums.
* Add a Follow/Unfollow button into the header bar of forums to add it to
  "My List"
* On the Categories page, a special "My List" category appears at the top
  if the user follows categories, with their follows in alphabetical order.
* On the Categories & Browse pages: forums you follow will have a green
  bookmark icon by their name.

Permissions:

* The forum owner is able to Delete comments by others, but not Edit.

Notes:

* Currently a max limit of 100 follow forums (no pagination yet).
