Gui: Add a context menu to select obstructed items (from RT fork)

Browse Source 
As the title says, this is from RT's fork. I only adjusted it a little
bit and removed pie selection which was previously in the
implementation.

To activate context menu - "G, G", then if it can't resolve edges vs
faces, it adds QMenus on top to let user decide which one to select.
