Sketcher SwitchVirtualSpace

Description
The FreeCAD Sketcher has two virtual spaces on which constraints can be set. Usually all constraints gets set on virtual space one. You can move some constraints to virtual space two. This can help to inspect only on a few constraints at a time.

Usage
To move constraints to the other virtual space: To switch the virtual space:
 * 1) Select constraints you want to move.
 * 2) Press the button.
 * 1) Make sure you have no constraint selected.
 * 2) Press the button.

if you decide to set constraints on the second virtual space, don't forget about them later on if you don't see them in the 3D view.
