Convert all occurances of PPS Client to Flying Agenet Client. And adjusted all other occurances of PPS accordingly

The coordinator row and (dis-)connect,  start-stop bar are now fully connected and fully generalised for operating as both an agent and a coordinator GUI

Added things to GUI: red rectangles to indicated an occluded measurement, and unavailable image for battery and flying state

Yaml connections working (for student and demo controller), and title is now proper. Ready for testing on real system before cleaning up the controllers and their interface

Connection between Coordinator and other components of GUI now working for passing around the agentIDs to coordinator. Next step is to clean things up, add all the necessary connections, and test.

Started connecting the Connect Start Stop Bar of the GUI. Now needs some GUI settings to be changed with Qt

Added files for the flying agent GUI, currently compiles in Qt but need significantly testing and development for integrating with ROS
