Add maximum train size

[GoogleCodeExporter]

Some users would like to set maximum train lengths so that the layout does not 
get overwhelmed when random chance or cargo settings send too many cars to one 
location.

There should be a maximum train length that the code for assigning freight cars 
to trains would respect.

The check for max train length needs to be done when assigning cars (so cars 
have a chance to be assigned elsewhere).  Algorithm will need to keep track of 
the number of cars added and subtracted at each station so it can tell when the 
between-station train length would be too long.

Potential implementation: keep an array of length [number of station stops], 
and mark the number of cars that are added and removed at each station.  When a 
station appears twice, we can either add at beginning and remove at end (must 
be done for first and last stop), or all switching can be assumed to be done at 
first occurrence.

For extra credit, go through cars in order of popularity of pick up / drop off 
station so that cars only picked up by one train aren't dumped because too many 
cars were added at a station served by other trains.
