Title: Bulk load zipcodes for speed

I found myself running setup multiple times (separate issue with timestamps on seed data), so this became a pain point:

````
time rake zip:import
Importing zipcodes (This may take a while)
43191 zipcodes sucessfully imported

real	2m28.246s
user	1m31.370s
sys	0m11.850s
````

I tried a SQL bulk insert instead:

````
Importing zipcodes ...
43191 zipcodes sucessfully imported

real	0m12.184s
user	0m9.140s
sys	0m0.560s
````

5 seconds of that is the Rails environment setup, so this is about 20x faster.
