Runtime correction of faulty eng parameters

Registered by Carlo Santucci

.eng files often have faulty values for some parameters, as e.g. AirBrakesMainMaxAirPressure and AirBrakesCompressorRestartPressure. This results in difficulties in brake applying and releasing. Therefore parameters are checked at engine load time and internally corrected if outside of an acceptable threshold. The specification URL refers to the ET forum discussion.

Also dynamic brake parameters often have questionable parameters, see http://www.elvastower.com/forums/index.php?/topic/29082-trainbrake-problem-with-acela-hhp-8/ .
Also these parameters are checked at engine load time and internally corrected if outside of an acceptable threshold.

Whiteboard

16/8/15: first release out with x.3219.
18/8/15: adjustment of compressor charging rate now performed only if the option to correct .eng parameters is checked.
24/8/17: with release x.3931 also DynamicBrakesDelayTimeBeforeEngaging and DynamicBrakesMaximumForce if outside reasonable threshold are corrected if the option is checked.
3/9/17: with release x.3939 also values of DynamicBrakesMaximumEffectiveSpeed and DynamicBrakesFadingSpeed are exchanged in case the first is smaller than the second (also if the option is not checked), which would lead to a faulty interpolation table.
