Minor fixes arising from the first practical class of Spring semester 2019. Mainly relating to loading of paramters on first run, and also the integrator of the default controller

Restricted Default Controller setpoint to be within the bounds. Fixed error in the safety check of the flying agent client.

Added message so that the default controller informs the flying agent client when a manoeuvre is complete

The test motors controller is now integrated to the flying agent client. The Default controller has the z integrator turned on, and the setpoint smoothing was slightly changed

Fixed abs() int casting causing errors for default controller state changes. Added integrator to default controller. Needs testing and adding buttons to GUI for run integrator and reset integrator.

Default controller compiles and is tested. Once remaining discrepancy is that the default controller switches into integrator mode too early

Finished implementing the Default controller (except for the integrator). Needs compiling and testing. (Also changed the ClientConfig.yaml to be FlyingAgentClientConfig.yaml)

Setpoint changes now generalised through the GUI for the Default controller. Needs more extensive testing. Next step is to get that current controller state when the corrdinator is coordinating only one agent
