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

Forgot to pull before committing
