Path planner: Move the types of path segments into the FlightDataModel and have the dialog
pull the information from there.  Also, when showing the mode param for circles call it
radius.
WaypointDialog: Add doxygen comments
PathPlanner: Move the waypoint data delegate into its own class
Path Planner: Use the delegate for the table
Path Planner: Make the waypoint delegate inherit from QStyledItemDelegate
Path Planner: Make sure the width of the columns is enough
Path Planner: Fix the delegate so the QComboBox for mode only appears when editing
starts.
Path Planner: Get rid of the relative position representation in teh FlightDataModel
Path Planner: When the mode editor dialog is not present then just show the text
Path Planner: Remove unused options from dialog
Path Planner: Get pushing waypoints directly from LLA working again
Path Planner: Fix issue where the Mode was not being sent to the UAV correctly
because the Qt::DisplayRole returns a QString instead of the numerical value.
Flight Data Model: Suppress some warnings.
Model Map Proxy: Also use Qt::UserMode when getting the Mode to get the numerical version
Path Planner: Show an NED column set too that are computed on the fly.  I don't like
that this requires the FlightDataModel to know about the home location.
Path Planner: Make it possible to set the coordinates by the NED values.  This has
to emit the columns that change accordingly for everything else to update the display.
Path Planner: Make the dialog show the relative location as well and allow
it to be edited.  The QDataWidgetMapper doesn't seem to catch changes
from the model to the widgets so when an NED coordinate is changed the
LLA version doesn't update automatically.
Path Planner: When the model changes call the revert method on the mapper
in order to show the updated data.
Path Planner: Bring back the locked flag.  The only thing that doesn't work
is locking the waypoint from the dialog box.  For some reason hooking the
submit and revert signals together is interfering.
Path Planner: Remove a few unneeded lines.
