(svn r7446) -Feature: Double the length of the cargo and rating indicators in the station list window,

thanks for the inspiration Rince. Workings of the small 1-pixel wide bar have changed a
 little. Up till now it was pretty random, now it is only drawn for stations with minimal
 amount of cargo (<=30) and 1-pixel height is 5 units.
