Made the maximum step duration 20 seconds for the CS1 controller. And changed the default values displayed in the fields

Added vertical banner to all GUI tabs indicating whether that controller is active not. Tested in simulation (there is a small chance this causes the GUI to occassionaly crash becuase of simultaneous setting of the properties of the banners). Tested in Simulation. Also fixed small mistake in the coordinator launch file

Fixed the error causing the coordinator to not work (the coordinator.launch file was not zero padding the coordID)

Connected the CS1 integrator buttons to the GUI and tested to be working in simulation. Needs testing on the real system

VERSION NUMBER UPDATE: to reflect the upgrade to be compatible with ROS melodic. And the change of naming convention from teacher to (dfall)master

Purged the code of all occurances of the terminology teacher. This was replaced by either master or by System Config GUI

Tested to be working with a network of 1 teacher, 1 student laptop, 1 raspberry pi, and 1 student GUI laptop. Added line to Config.sh for how to run as a teacher (aka dfallmaster), and adjust Radio Emulator to wrap back around for command above 65535

Added Mocap Emulator and complete the Quadcopter Simulator class. Tested and working on a single laptop. Next step to test on a network of laptops

Finished updating the CMakeList so the GUI is compiled only when the necessary Qt packages are available. Also added comment to agent.launch file giving example of how to launch without the GUI

Fixed small bug for remote controller to subscribe to vicon data publisher correctly. Compiles, tested, and working.
