Allow the librarian to add/edit/remove tags from other people's projects.
Presently, a librarian can use the tag management view to add, delete, and edit existing tags. They can also merge tags. They can mark a tag as approved which will make it appear green to all of your users, and signal that its use is encouraged. But they cannot modify tags from other people's projects. It would be helpful if we can have a librarian add/edit/remove tags.
