Changelog:
FIXED
1. Ghost servos appearing in the VAB/SPH after removing a chain of 2 or
more servos from an assembly.
2. The "rotate" orientation buttons in the VAB/SPH is finally fixed. I
wasn't using the Rotate method correctly.
3. Servo will be hidden by default. Want it to appear, toolbar click it.
If you choose to not use the toolbar, it will function but the window
will always show.

NOT FIXED
1. Move "home" adjusted when the min/max have been changed.
