That's a good point.  I think for road building the MC should be 1 for tiles 
that can have roads and (terrain's move cost) for those that can't.  This way 
the above situation should be handled.  However it's not quite right since a 
single tile break in the road causes the full MP to be used for _2_ moves.  
Perhaps with more complex logic (checking the source tile) this could be 
handled.
