I've fixed the bug causing parameter changes to have no effect on the
drone. Now we do a proper setup of the drone tool (rather than using
the factory default), which includes setting up application and user
profiles on the drone to hold our settings. We then actually send the
parameters to the drone, rather than doing nothing. The parameters
system has been extended to allow all user-modifyable parameters to be
changed (see AR.Drone SDK manual).
