v2.7.4: Named location presets and tappable nearest-airport ticker

Browse Source 
Location presets can now optionally be given a name (e.g. "Home"),
shown in the overview instead of the raw coordinates. The
nearest-airport ticker on the Location Presets screen is now
tappable (shown with a thin green border) and adds that airport
directly as a new preset with its name and coordinates, using the
existing local airport database on the SD card - no internet lookup
needed. AirportLookup::findNearest() now also returns the found
airport's own lat/lon for this purpose.
