adding suffix for RC versions in version number (GUI, reports), adding explicit message that this version is not for certification

adding missing fields to MRF: vehicle model, name and address of manufacturer; torque limits in percent
new testcase
adapting output schema

add handling for a special case in driver strategy: vehicle declerates to new target speed, shift strategy decides to downshift, toruqe at gearbox output is negative (due to slope and other resistances), but torque at gearbox input gets slightly positive but the gearbox is disengaged - no driving force. trying again with roll action after overload fro brake action.

DrivingCycle Reader: add stop time for first entry if stop-time is 0, duplicate entries with stop-time = 0

allow slipping clutch also in second gear (required in construction cycle with limited engine speed)
