Drop like a stone mode in planner

Most of my dives i plan i know it will just be full speed down a line in
the beginning and thus the planner can figure out that leg of the plan
by it self.

The config box added here isn't connected, because i saw that the other
planner boxes wasn't connected ether, so i left it in the same state as
they where.
