* commit '98d51129':
  change label text
  fix testcases: mock gearbox has to return geearinfo, measured speed / pwheel mode cope with EngineSpeedTooHigh response
  adding test for engine speed limiting
  adding testcases for torque limits, gearbox speed limits
  major refactoring: use multiple full-load curves, one per gear. introduce vehicle-defined limits and gearbox-defined limits
  remove 'old' gearbox maxTorque limitation, add gbx. max speed limitation
  max speed for gearbox: adapt gui, json reader/writer, xml reader/writer, testcases (xml)
  reading and writing of torque limits (vehicle) implemented
  refactoring vehicle form for torque limits input
  remove input (gui, interfaces, json, xml) for engine start/stop
