changing thermal de-rating model of electric motor. adapting GUI, adpatin json file formats, adapting testcases

introducing new response in case actual engaged gear differs from gear used in hybrid strategy evaluation - catch in hybrid controller and re-calculate with new gear

if no thermal degrading is available in input data set it to high values (i.e. disable thermal buffer)
provide debugging info (toString method) on hybridstrategy response, hybridcontroller response and em-settings

implementing electric machine de-rating: adding testcase, new model parameters (gui, writer, inputdata), adapt existing motor files,

fix case where gearshift happens and braking results in negative braking power - perform roll action

new feature: allow engine off only if ESS is enabled in the vehicle. new testcases, new modeldata (allow ess for existing models)

testpowertrain hybrid strategy: initialize engine auxiliaries to use correct angular speed for calculation
