Ref T12956. UI changes:
- Administrators get a new [X] Save as global query option when saving a query.
- "Edit Queries..." is split into "Personal" and "Global" sections. For administrators, each section can be edited. For non-admins, only the top section can be edited, but any query can be pinned.
A couple notes:
- This doesn't support "pin for everyone by default". New users just get the first query from the bottom set. That seems reasonable for now.
- Reordering is currently a little buggy (it works if you've reordered before, but not if you're reordering for the first time), but I need to migrate before I can fix / test that properly. So that'll get cleaned up in the next change or two.
