FIXED non admissible velocities should not be weighted with zero obstacle evaluator vote, but should be forbidden at all

DwaNavigator/DwaProblemOptimizer.cs: Evaluate could return minus infinity, which would mean forbidden velocity
DwaNavigator/DynamicDiamondGenerator.cs: exponential prediction of velocities implemented
DwaNavigator/DwaNavigatorService.cs, DashboardService.cs: iteration number introduced to service state and to DashboardService
