Merge of pre-Spring 2019 semester updates into the master

See merge request D-FaLL/PandS-System/D-FaLL-System!12

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

Fixed System Conig GUI so that objects with naming convention CFXX are plotted as question marks for an XX id that is greater than 9 (previously nothing was plotted)

Updated installation script to match current naming conventions. And updated installation wiki page to match.

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

Completed redevelopment of the Flying Agent Client and GUI, and the Default Controller

See merge request D-FaLL/PandS-System/D-FaLL-System!11

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)

Now compiles in ROS. Flying agent cleint seems to work well with the new structure. Default controller still needs implementing

Mostly finished with converting the Flying Agent Client to the Default controller. Needs comoiltion testing. Next step is to make the Default controller able to perform take-off and land manoeuvres

Add bits and pieces to the Slying Agent client for checking availability and occulsion of mocap data. Needs compiling and teesting

Started process of converting the Flying agent client from the safe controller to the default controller, and streamlining things at the same time. Currently compiles and flys, but needs cleaning up and proper implementing of the take-off and land functions.

Small changes to the picker controller for paramter loading, and to Flying agent GUI for units of the yaw error

Renamed launch files to begin with a lowercase letter to make it easier for typing into the command line

Updated wiki and install folders for the change from pps_ws to dfall_ws, and from d_fall_pps to dfall_pkg

Fix to C make list for the naming of the flying agent and system config GUIS (the first letter needed to be captialised)

Started process of adding a template controller. Still need to connect the GUI elements and add the ROS Controller Service node

Remove the StudentGUI because it is was not updated to the new node naming convention and because it was re-factored as the FlyingAgentGUI
