Support cut/copy/paste of several regions and lines at once.
The idea here is to do the reasonable thing, and copy objects of some type (e.g. MIDI region, gain line) to tracks with a matching type. The user can override this with a track selection, which will be used straight-up. Lost: ability to copy/paste lines across types, e.g. gain to pan. This is often questionable, but sometimes useful, so we will need to implement some sort of "greedy mode" to make it possible. Implementation simple, but not sure what to do. Perhaps this should only be possible if one automation track is explicitly (i.e. via track selection) involved, and the types are at least compatible-ish?
