Ability to set zip_code wrong zip penalty

[robe]

Right now the zip code penalty is hard-coded in the code and a function of abs(edge_zip - input_zip)*somenumber.

I've found what I have in place is generally too low at least for cases I've run into. Rather than just up it, I'd like to make this configurable.
