Torsten Dreyer 5caa42af8e Make use of auto-coordination more flexible 
- move property /sim/auto-coordination to
  /controls/flight/auto-coordination
- introduce new property /controls/flight/auto-coordination-factor
  with default of 0.5
- auto-coordinate the rudder if auto-coordination is true and the factor
  is greater than zero

backward compatibility for the old property is temporary provided by
a temporary Nasal hack in FGDATA/Nasal/aircraft.nas
