Depends on D20353. Ref T13275. This is just some small quality-of-life fixes:
- When you add items to menus, they currently go below the "Edit Menu/Manage Menu" links by default. This isn't a very good place for them. Instead, lock "edit" items to the bottom of the menu.
- Lock profile pictures to the top of the menu. This just simplifies things a little.
- Show more iconography hints on the "edit menu items" UI.
- Add a "drag stuff to do things" hint if some stuff can be dragged.
