[new feature] Sketcher Arc of Parabola

Dear all,

Recently Arc of Parabola support for the Sketcher has been merged, so now it is possible to use an Arc of Parabola in your sketches.

This should allow to do, for example, designs of parabolic offset reflectors of satellite antennas (typical small parabolic antennas use for sat tv). I have tried to do mine as a fast test. However, I am not good at doing actual mechanical design... anyway, I managed to do a reflector... somebody may come with a full antenna with LNB and wall attachment in the showcase forum.

N.B.: The datum line is the X axis direction of the paraboloid. The datum point is the focus. I love part design NEXT. It is really cool.
