The link support means that an object can now appear in more than one
places, and even inside a document different from its own. This patch
adds support for in-place editing, meaning that the object can be edited
at correct place regardless where it is.
See [here](https://git.io/fjPIk) for more info about the relavent APIs.
This patch includes two example of modifications to support in-place
editing. One is the ViewProviderDragger, which simply adds the dragger
node to editing root node by calling
View3DInventorViewer::setupEditingRoot(dragger). The other much more
complex one is ViewProviderSketch which calls setupEditingRoot(0) to
transfer all its children node into editing root. ViewProviderSketch
also includes various modifications to command invocation, because we
can no longer assume the active document is the owner of the editing
object.
This patch also includes necessary modification of the 'Show' module to
support in-place editing.

Because of path based rendering (SoFCPathAnnotation) in mouse over
highlight, this bug causes crash more frequently here comparing to
upstream.
All C++ calling of SoGroup::removeAllChildren() is replaced by
Gui::coinRemoveAllChildren(), and python code is fixed by monkey
patching SoGroup.removeAllChildren() in FreeCADGuiInit.py.
=================================================
the position obtained from the SoPath of the picked point when entering
the combined icon object is not the center of the icon, what leads to
wrong preselection or no preselection at all.
This commit uses the translation of the Constraint node, which is the same that
is used to locate the constraint icons on the screen in the first place.
========================================
Now the Grid is calculated based on the maximum semiaxis length. Grid is recalculated on every redraw of the Sketcher.
========================================
Axes size was bounded to the boundingbox of the underlaying 2D shape. However, this does not even get updated in no update mode and provides unreliable values.
The axes calculation now:
- is coded to be the same size and fully symmetric.
- is coded to be minimum 100 mm semiaxis, which gives a good impresion for empty sketches with default zoom.
- is coded to grow with the largest of the semiaxes.

Deletion of coincidents rely on selected vertex. The original code was trying to delete a coincident without checking whether one was there.
The implementation now relies on checking whether a coincident is present.
