correction of a bug. On one car, the door open on the wrong side

version 1.1 improvement :
-some people said that they have difficulties too put the car in the good order. Now you will find complete RIB trainset in the multiple unit menu. From now the separate cars are not available in the car menu. But if you want your own custom trainset like before, with TFMM you can activate an option (look at the first image) and they will show again.
-reversibility
-new light system
-correction of the passenger feet problem. Thanks to Onionjack_ to give me a tip in comment on steam.
