Improve Menu experience

[mireillesan]

If possible, please make it easier to delete multiple menus with a one click button (same as the plugin interface).
For example add an extra tab next to "Manage Locations".

• Right now, we've to select a menu (to edit) then remove it. If you have like 10 menus... then this task simply takes too much time.

The menus are saved all over different tables wp_terms, wp_posts, etc. inside the database. Wouldn't it be better to simple create a seperate db table for menus instead and have all data placed in there (with object cache)?
