DrivingCycleDataReader: Set PTOActive to false when duplicating distance entries due to 0km/h and stop.

AxleGearLossMap and PTOLossMap: Changed Handling of empty values (no exception, instead return null value)

Merge pull request #246 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:bugfix/VECTO-327-tc_loss-0 to develop

* commit 'd5d207dd':
  when disengaged: at gearbox input speed (and torque converter speed) is 0
  change code to have a brakepoint when tc-loss < 0

Merge pull request #245 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:feature/VECTO-328-Remove-TC-GUI to develop

* commit 'b027c418':
  removed torque converter column in list view
  substitute column indizes in gear listview by symbolic names
  refactoring listview for gears, use named colums, method to create entries

* commit 'e2ddd761':
  Aux Tests corrected
  SumWriter: Performance Optimizations
  VSUM: Corrected wrong P_TC_loss column

* commit 'a6b4a69e': (21 commits)
  ComputeAcceleration: more intuitive formulas
  DrivingCycleDataReader: Aux Column check corrected
  PT1: Problem with range check solved
  Auxiliary-ID: Problem with different cases (lower/upper) solved
  Faster IsSmaller and IsGreater
  Gui Mainform: Made Start Button bigger
  CycleClutch: Corrected wrong switch statement. Now only underload is checked.
  CycleClutch: Added Search for Idling-Operating point if ResponseUnderload from Engine
  DrivingCycleDataReader: Corrected mandatory and allowed columns in MeasuredSpeed Cycles
  CombustionEngine: Faster IsSmaller and IsGreater function calls
  added default value for inherited argument
  comment
  CycleGearbox includes Inertia in DryRuns
  MeasuredSpeed: Additional Search if braking power was negative
  TransmissionLossMap: Is Now bigger when build with efficiency
  Fixed Error with current dir in FileDialog
  IsAboveUpShiftCurve, IsBelowDownShiftcurve: only minor tweaks
  added check for upshift if max gear is already reached
  User Manual: Updated description of driving cycles
  GUI: Removed IsTCGear Checkbox
