update user manual and release notes with more details on the input parameters for CNG/LNG vehicles.

fix in driver model: handle the case where the next target speed is exceeded because a slight target-speed decrease is not considered (current vehicle speed is still below next target speed) (UrbanDelivery Cycle)

Change defines for dev-build/release candidate. default build is dev version. add solution-wide defines

driver strategy: handle the case of a gearshift response separately as this may occur after an overload, e.g.

necessary if slight braking is required when accelerating from stop due to engine inertia (special case, vehicle stops too early when halting uphill)

gearbox: additional criterion for disengage before stop driving downhill (neg. torque): gradient has to be negative or in-speed below idle speed

driver strategy: slight acceleration after a too early stop may result in underload (due to high engine inertia) - apply brakes

driver strategy: handle the case that the vehicle stops before a requested stop in the cycle due to disengage.

if the vehicle stopped already but did not reach the stop distance, accelerate for half of the remaining distance until stop.
call handleTargetSpeedReached only of the vehicle is not stopped

Gearbox: set torque loss to 0 if angular speed is 0. already done for transmission component and gearbox when disengaged. added for engaged gear.

make testcases run: return null for brakin action in case the gear changed and the response gets an overload response; adapt tolerances for at moddataintegrity tests
