custom controller a bit more ready, still need to fill information in GUI fields and connect everything to GUI (set setpoint mainly). Landing and take off parameters now in YAML file

created install script, removed shitstack.txt, corrected small compilation error for CentralManagerService.cpp

solved issued on data record. extended Student.launch with rqt dashboard plugin to send manually configured topics.

Previous commit made something to not work.. Reverted to a6c20a60 and added Debugging.msg, and two new launch files (propbably unfinished)

rosbag included. not working and creating error at startup. rest should however still run. safetycheck added again ... switches off and terminates ros when area boundaries are left

changes to CMakeList, Crazyflie.launch and CustomControllerService -- all concerning the CustomControllerService

changed the function convertIntoBodyFrame(request, est, state, yaw_measured) such that it uses the measured yaw without considering the setpoint - eliminates the drifting problem but is probably still wrong regarding the controlling logic. Added an rqt-plot to the launch file.

supposedly fixed problem caused when multiple Cf-Objects are selected in Vicon. Plus some cosmetic changes
