bug in 3D flypath generator

sjf

When I make a 3D fly-path (line and nodes) and populate this, the last node will have a speed of zero (0) and when you adjust the parameters and want to save it will report an error. Speed can not be 0. when you fill in 1 (or something) the adjustments will be saved: but not the speed. So every time you adjust you have to change the speed.

annoying, not unworkable. Speed should be saveable.
