Maneuver/VehicleFormation/FormCollAvoid: Added the capability of rerouting the plan activation message. Control of activation of the task, both for real vehicle control and for virtual leader simulation. Added activation control for the formation controller execution.
Config: development/form_fl: Changed the default vehicle, the debug level and the messages sent to the virtual leader.
Config: development/form_lead: Changed the plan database path from x8-00 to x8-01. Changed the default port for communications with CCUs. Enabled the printout of received messages from the real vehicle DUNE.
Config: development/uav_sim2: Changed the alternative UAV simulation configuration to a 5DOF simulation model. Activated the printout of messages received from Neptus.
