1) The chat menu will now select the runway closest to the aircraft
   when the aircraft is on the ground, or very low (< 100ft). This
   handles the case where the user has selected a runway explicitly,
   e.g. 01R for KSFO take-offs for noise abatement. My thanks for
   AnMaster for pointing this out on IRC. Note that above 100 ft, the
   wind-appropriate runway will still be used.
2) Change to keyboard description for the - key, as pointed out by
   Melchior.
