(svn r18404) -Codechange: link drive through stops better together -Feature: make penalty for road stop occupancy user configurable -Fix [FS#1944]: road vehicles would not pick an empty drive through stop. Now they will *if* the penalty for driving around is less than the occupancy penalty -Fix [FS#1495]: long (articulated) road vehicles could block loading of others when the following road vehicle already got 'permission' to go to the next bay even when it could not reach it -Change: improve the throughput of the drive through road stops by letting them stop closer together
