In pedigree editor do not show A&W options on hoverboxes for patients which are read-only for current user

If a node is read-only in pedigree editor, attempting to open node menu correctly displays "you do not have edit rights" message. However clicking on one of the A&W options in the hoverbox results in "can't apply changes" error.

Instead, any edit tools should be hidden for nodes which are read-only
