[Suggestion] Allow company owners to define bus models

Currently almost all buses in our depot show incorrect models. (I can count the correct models on one hand). Make it so that company owners can choose from existing model list how the bus looks like in BCS.
I know BCS supports the citaro bus models and solaris bus models, we have a lot of those buses but all show either C2 model or no model at all because we have slightly modified versions (morphi versions and Poland Megapack versions) but then again we could set them to look like the existing models which actually already exist in the BBS.
