Allow deleting imported waypoints

[wsnyder]

I import waypoints from e.g. a kml file.  I then use Waypoints->Manage waypoints to put them onto my map, and can see them of course.



However when I click on one of those waypoints there is no "delete" as with manually created waypoints.  Please make a delete button - or at least a "remove from map" button.   The only alternative way to do this now is to delete them in the waypoint manager, but to do that you need to find the proper name for the coordinates of the waypoint to delete, which is obviously quite inconvenient.



Thanks.
