-RM-220-MR-Support NVidia optimus (optirun) in OpenWalnut startup script.
using @optirun bin/openwalnut@ does not work as expected. The script does not transport the $DISPLAY variable properly. Optirun usually uses display 8.
To allow optirun set the correct environment, we need to integrate it into the bin/openwalnut script.
