app: in GimpDial, add "clockwise-angles" property ...
... and rename "clockwise" to "clockwise-delta" Add a boolean "clockwise-angles" property to GimpDial, which, when set, causes the dial legs' angles to be measured clockwise, rather than counter-clockwise. The property is FALSE by default. Rename the "clockwise" property, which controls the direction of the measured delta between the two angles, to "clockwise-delta", to avoid confusion, and adapt the rest of the code.
