DUNE/Simulation: Added altitude control through pitch commands to the 4DOF_alt and 5DOF simulations models.
Simulators/UAV: Added support for pitch commands to use with the 4DOF_alt and 5DOF simulations models.
Maneuver/VehicleFormation/FormCollAvoid: Added the capability of rerouting the plan activation message. Control of the task activation, both for real vehicle control and for virtual leader simulation. Added activation control for formation controller execution. Changed the way simulation model commands are accessed.
