+ fix SoAutoZoomTranslation and SoZoomTranslation to get correct scaling factor
(do not rely on active view because this can be the wrong one and thus delivers wrong results)
Jog, drill, linear and arc motions works.
Tested on machine with some trivial projects,
dimensions and feedrate speeds verified.
Safe-Z/clearance command currently not respected (defaults to max height, super conservative).

First bug: Inability to create links to external geometry as described here:
http://forum.freecadweb.org/download/file.php?id=16668
Second bug: FC crashes on changing the support after having imported external geometry as described here:
http://forum.freecadweb.org/viewtopic.php?f=10&t=12380
and solving this ticket:
http://www.freecadweb.org/tracker/view.php?id=2225
Solution to first bug:
If for some reason a sketch ends up having a list of external geometries (property) that can not be recreated (rebuilt),
they remain latent, do not show the external elements in the elements widget or in the screen and prevent adding the
elements again.
In cases where the saved file contains invalid external geometry links (which will give raise to a handled exception that would prevent external geometry creation),
this condition gets detected during restore and the invalid links are deleted before external geometry creation, so as to allow the rest of external links to be recreated.
Solution to second bug:
It is also related to invalid external links (the link was existing, but upon change on the support, it is possible that an external edge is no longer valid, reduction of edges in support).
This situation is detected upon entering into edit mode, and the invalid ones are deleted.
Note that there is still the possibility for the user to remap an invalid sketch BEFORE editing, if the remapping is successful, it may not be necessary to delete links (all depends on the
specific case).
Since getTypeName() returns None for None and default both must be handled the same way in other switches.
After applying following bug will be fixed:

What is this?
method
getCoincidentPoints
actually only included (as indicated in the documentation comment) those points coincident by a single constraint.
That is not "all the coincident points".
However some methods currently using it are expecting exactly that (coincident points linked by a single constraint).
A new method is introduced:
const std::map<int, Sketcher::PointPos> getAllCoincidentPoints(int GeoId, PointPos PosId);
that provides all the points coincident with the given one, directly (via a single constraint) or indirectly (via multiple coincident constraints).
The old method is renamed to:
getDirectlyCoincidentPoints
So as to have a more meaningful name to differentiate between both methods.
======================================================================
1. SketchObject::arePointsCoincident upgraded to check for indirect coincidence.
2. Coincidence constraint creation now checks for indirect coincidences and avoids
creating redundant coincidence constraints (for example during box selection).
