Track Editor: Quick Multidelete of points

Sometimes, with bad GPS coverage, a track can get very "jittery". So in order to fix it with the track editor, I have to delete a lot of points that are not consecutive. So "Cut inner part" doesn't help. But deleting the points on by one is very tedious because of the additional menu.

I propose a "quick multidelete" mode: When started, all track points are painted as green dots (like in "Insert/edit trackpoint", but without the red dots in between, and preferably all points active). Now every dot you tap is deleted. Like with Insert/edit, you can discard your edit or accept it.

Would save a lot of time.
