David Megginson's changes:

src/Cockpit/radiostack.cxx
- extended VOR ranges to make them slightly more usable (pending some
  real radio code)

src/Cockpit/sp_panel.cxx
- fixed heading bug on gyro compass (sort-of -- the AP still doesn't
  work quite as expected)
- skid ball moves the right direction
- moved whiskey compass more to the co-pilot's side, as suggested by
  Alex a while back

src/Joystick/joystick.cxx
- included Norm's Windows patches
- renamed brake properties (see bfi.cxx, below)

src/Main/bfi.cxx
src/Main/bfi.hxx
- renamed getBrake and setBrake to getBrakes and setBrakes
- added getCenterBrake and setCenterBrake
- added getAPHeading (without mag correction, needed for the panel)
- renamed property /controls/brake to /controls/brakes/all
- renamed property /controls/left-brake to /controls/brakes/left (as
  requested by Alex)
- renamed property /controls/right-brake to /controls/brakes/right (as
  requested by Alex)
- added property /controls/brakes/center
- added property /autopilot/settings/heading
- fixed bug in setAltitude so that altitude will be property restored
  from a save file
- fixed getBrakes to return the highest of the three brake settings

src/Main/save.cxx
- call FGBFI::getBrakes instead of FGBFI::getBrake
