A new setting *edit controls which is a Pointer with these *options as checkboxes, which if checked do the following:
- link in menu - makes "Edit" link available
- double-click - makes double-clicking trigger editing
- require permissions - show / respond to edit controls only if the user has permission to edit the card
Note that these can be options in a "*edit controls+*right+*options" Pointer without actually adding cards with those names.
