20140111 - Add ?icao=ICAO to center map to that location quickly
20131217 - Get the FGTracker livewaypoints, and only mark callsign in BOLD if present in tracker
20131127 - Flight selection opens one new window - tracker.html
20131104 - Implement a column sort - geoff
20130927 - Modified to run in local context only - copied files from static.fgx.ch - geoff
