undo: remove only "non-protected" cylinders

Browse source 
The undo-code must take care not to remove used cylinders.
To do so, extend the constructor of EditCylinderBase,
which collects the cylinders and dives to edit, by the
"nonProtectedOnly" boolean argument. If true, only those
cylinders for wich "is_cylinder_prot" returns false
will be added.
