Add Meters/Feet Unit in X Y Z focus and "Meters/Feet per rev" option in manual control for encoders

Hi, 
i tried to change units of X per rev for encoders in user setup. Only way to achieve this is to edit X focus in Fixture editor and apply a "D" unit to X Focus.
It would be better to have meters or feet by default for X Y Z parameters and resulting options in setup

manual control
