19.6: Fixed bug with importing some KML files. Changed "Delete all" option to be "Delete all and reset". Added a "copy" button to allow copying grid refs to clipboard.

19.5: Added an option to set a "route" between pairs of waypoints using the "waypoint to waypoint" option on the waypoint menu. On preferences page, added options for the "goto" function to automatically switch to next waypoint in route, and also to set the proximity distance.
