This code is less relevent with the new L1 navigation, and could cause
issues with the pilot not having control after a long dive.
Thanks to Soren for pointing out the issues
See issue #305
when airspeed is below airspeed minimum. This is consistent with the
previous controllers

this switches ArduPlane over to use the L1 navigation controller, via
a generic nav_controller object pointer.
Note that the nav_controller controls all types of navigation now,
including level flight and heading hold. This provides a cleaner
abstraction than the old method of special case navigation handling

this makes FBWB much less sensitive to airframe tuning. When the
elevator stick first goes neutral it locks in the current altitude as
the target altitude. When the elevator stick is off neutral, it moves
the target altitude in proportion to the elevator, at a rate goverened
by the new FBWB_CLIMB_RATE parameter
This prevents the aircraft from slowly drifting in altitude in FBWB,
and gives a more intuitive control mechanism for altitude.

change
this allows control over whether ArduPlane tries to hold heading
during auto takeoff. For hand launches it can be better to hold the
wings level and not attempt to hold heading during takeoff to prevent
the possibility of a stall during the climb out.
Thanks to Chris Miser from Falcon UAV for the feedback that led to
this option.
- libraries/AP_Common/AP_Common.h: Use bit 2 of Location.options to store
loiter direction
- ArduPlane/defines.h: New bitmask MASK_OPTIONS_LOITER_DIRECTION for struct
Location bit 2
- ArduPlane/ArduPlane.pde: New variable loiter_direction
- ArduPlane/GCS_Mavlink.pde: For mavlink loiter-commands use sign of param3 to
detemine direction. Set Location.option flag accordingly
- ArduPlane/commands.pde: Make sure loiter-directions get saved into EEPROM
correctly
- ArduPlane/commands_logic.pde: Set loiter_direction on all loiter-actions
as well as RTL/instant loiter
- ArduPlane/navigation.pde: Yield loiter_direction in update_loiter
