Select an aircraft by clicking its track on the map

Problem:

On a busy map with many overlapping tracks and teardrops, it's hard to pick out and select the correct aircraft.

Desired outcome:

Select an aircraft directly by clicking its track line on the map, without hunting through the aircraft list or crowded markers.

Proposed change:

Make aircraft track lines clickable — clicking a track selects that aircraft (its latest track) and opens the point info at the latest point, the same result as selecting the aircraft from the list.
