Lots more map work, mostly around switching from "construct a big HTML string"

Browse source 
to working directly with the DOM to update the table / selected plane info.
Seems to speed things up (and deflicker them) a lot.

Also stable sorts, allow disabling the clocks, draw ground tracks in a different
color, put "last seen" info on the selected plane infobox, if position updates
are infrequent then combine them into a single estimated line so that dash
placement works properly, probably a bunch of other things..
