only some small additions for data recording. safecontroller is also writing to bagfile allowing to find the controller mistake.

added image to project. Need to adjust size, offset, etc. Need also to investigate CMAKE resource adding

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

Finished with controller, therefore we merge

Merge branch 'controller_update' of https://gitlab.ethz.ch/D-FaLL/D-FaLL-System into controller_update

This has to be done
