Change ROI to use value 201 instead of 80

Changed this value in the enums that MAVLink uses.
Enable ROI value 80 again
Change waypoint type selector to use correct ROI
Remove old ROI from editor listing

Removed ROI listing from editor screen that uses the incorrect value.
This is displayed by the waypoint editor once you select a waypoint from
the Planning Screen.
