Reconnection working now. Need to discuss if it is better to have scripts called from GUI or the way it is done now

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

Added some changes to try downstairs: Scale factor 1.2, take into account occluded flag in controller, Z origin is now 0, table, not middle of box

Kind of solved the problem, need to test it more. Commented out the on_tabWidget_current_changed. Need to check if we need it for something

Discovered that we crash when we press multiple times loadfromDB button in GUI. It also doesn't work properly
