bug with routes, cf. issue #5
added method that displays points live

too slow with the processing on client side.
livePts process is now server-side

also changed "Point" with "Geometry" in db research functions
added livetracking button & query opts
added selective refresh

a little faster but still too long. do not know whether the improvement
is due to independent calls server->FR and page->server or to the
selective refresh (reduces the data only by 50% on avg)

datasources are no longer geoJson
added terrain views and factorised some functions
added a try for homebutton + minor changes
added selective refresh

a little faster but still too long. do not know whether the improvement
