I went through the AI code to put the "bank" node back into the config file,
so the models can fly circles.  While I was in there I made some other
changes.

*)  Moved the initialization of roll, tgt-roll, pitch ... etc, from init()
into the constructor, so it wouldn't over-write the config settings.

*)  Changed the altitude getter to remove the meters-to-feet conversion.  The
altitude is kept internally in feet.  Only the scenery code needs meters.

*)  Added "bank" item for config file (for type=aircraft).  Left bank is
negative.

*)  Added "rudder" item for config file (for type=ship).  Left rudder is
negative.  Internally this is stored in the "roll" variable, but the ship
model doesn't roll.  It uses the "roll" variable for turning though.

The following puts a tanker at 3000 feet, 6 nm northwest of KSFO.  On takeoff,
the tanker is visible over the hanger building at one-o'clock.
