Instead of deleting all table contents, actually remove the entire file on disk and re-create. This is fractionally more work, but removes any possibility of stale indices or missing deletes causing clutter after rebuilds. My suspicion is, this is cause the erratic performance some people have seen with the airports search dialog, so will back-port to 2.10.
Comments in the code imply osgViewer always sends 'num-lock'-off codes, but that is not the observed behaviour with Cocoa. So adding mappings for the num-locked codes on Mac, which is what people actually want at the moment.
Enabling this hack by default, to assess the impact for everyone. Should fix the issue for Ati Catalyst 11.5 users, and hopefully no impact for everyone else. All feedback appreciated. Set /sim/ati-viewport-hack to false if you think this option might be causing issues for you (and then tell James, ASAP)

AndersG noticed an issue when a ground-net file is edited. The DROP commands prior to the reload were wrong, fixed now to delete all ground-net entries before the file is read.
KATL -> KLAX looks correct now. Great-circles that span the 180-meridian are still rendered wrong, but that's a map projection issues, which I will fix in the next few days.
This allows delegates to take action when the flightlan is cleared, and especially, for the default delegate in the route-manager to deactivate itself, and hence the GPS LEG mode - which fixes bug 940 I hope.
When leg spans more than a threshold (currently 0.5 degrees) of longitude, interpolate the actual path flown by the GPS/RM, which is a true great-circle. Previous we rendered a Rhumb line which does not agree at all. (Especially noticeable in the MapWidget and NavDisplay code, both of which use RoutePath to tesselate the route before rendering)
At large search ranges (320 or 640NM range on the 777), the search time can blow up, especially if distant airports are being loaded. Add a time-bounded spatial query, and use it, so performance stays tolerable.
