feat(editor): a slip is selected, slid and deleted whole: any track of it picked shows all of it selected, editor_mode::slip_of finding its switches by its record, the tracks between them and its four ends. Dragged along, the slip moves along its first track with the straights out to the joints of its template and its crossing track, as far as that one goes on into tracks with their ends free, the straights of its first track before it and past it lengthened and shortened, a metre of them kept; one bent into a curve isn't slid, nor one whose crossing track is joined on beyond it. Deleted, it leaves its two tracks crossing from end to end in its place, kept in the scenery as a crossing Skrz, as a switch leaves its main track; Shift+Del takes all of it, Ctrl+Z brings it back. Selftest: a Rkp laid with its crossing track slid 5 m on and 3 m back, the joints of its template with it, walked through; deleted into a crossing Skrz 1:9 walked through, back with Ctrl+Z; a Rkpd at a crossing of straights with free ends slid 2 m, deleted into a crossing
