Cut (Ctrl-X) marks the selection on the clipboard with a `cut` flag; a paste of a cut from a real playlist is a *move* (single-undo across playlists via move_tracks_between_playlists; same-playlist reorders), while a copy — or a cut from the library, which has nothing to remove — just adds. Paste now inserts *above the selected track* rather than appending. Cut/Paste added to the track context menu; parse_tracks_mime now tolerates a None/empty clipboard.
