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.
Before that (e.g. on MacBook Pro) it was very hard to see the microscopic selection-circle hidden behind much bigger cursor arrow when trying to snap e.g. a line to some vertex. Now this setting can be used for such displays to increase the marker size and make it clearly visible behind the cursor.
The already existing "sketcher marker size" property is intended to be used for sketcher only, so it's not suitable for global setup of all the markers' sizes uniformly...
