John Beard ff31b88857 Pcbnew: add keep-radius arc-edit mode
This is (now) fairly easy to slot into the PCB point editor
framework.

In this mode, the endpoints adjust only the endpoints on the existing
radius. Radius can ve changed with the midpoint point. The center
point moves the arc, as in the "keep center/adjust radius and angle"
mode.
