Geodetic reference: Corrected firmware to use mean seal level altitude.
Note, the tablet altitude needs to be resolved.
Geodetic reference: Clarified text box instructions.
[CONFIG]: Fixed bug by which output channel assignment text could be out
of sync with output channel assignments.
On the advice of a Qt developer ("Just put that header file in the .pro
and be done with it") this fixes the issue where SysAlarmsMessaging was
not recompiling when the SystemAlarms UAVO was changed.
[CONFIG]: Removed superfluous code.
Failsafe: only enable stabilization when armed

If the system is disarmed when failsafe is engaged disable all
stabilization to make sure control surfaces do not respond. This
means a transmitter is required now to test the and tune the gains
on a fixed wing.
ComplementaryFilter: use z-axis correction from accels

This doesn't matter normally when board is horizontal but
when at strong pitches or rolls this correctlys the
perpendicular axis.

Not applying to the integral component since during most flying
this won't be useful or could only add noise and the mag is
more useful for this axis.
KMLExport: Added airspeed to export map. Also changed timespans to work on
flight path lines, making it easier to follow the vehicle's trajectory.
[KML export]: Changes requested in review.
[STABILIZATION]: 1) Enhanced coordinated flight to include a yaw damper when
flying straight.
2) Added separate field for coordinated flight control gains.
[Coordinated Flight]: Removed bound from coordinated flight. Now the
vehicle will attempt to return to its original heading even in strong
winds.
[Coordinated flight]: Changes requested in review

1) Got rid of magic numbers.
2) Nested if statement.
Adds different VirtualBar parameters to TxPID
ManualControlCommand: use named channels

The channels field of ManualControlCommand has mapped to named
channels for quite some while but the fact it just shows us as
a vector lead people to believe it was related to the order of
the underlying driver layer.  This should decrease that
ambiguity.
[QML PFD]: Fixes an issue by which the PFD was continuing to process
events even when it was no longer visible. This specifically sets the
processed states to 0 as long as the PFD is not visible, and sets them to
the corresponding UAVO when they are.

On OSX with Qt 4.8, this saved 14% processor load.
