Form Updates + FPAC's Food Resources

+ Replaced manually-generated drop-down menus with wtform’s `SelectField`. (Fixes issue #37).
+ Uploaded CSV files with all of FPAC’s resources.
+ Wrote script to create `FoodResource`s from FPAC’s list of resources. (Run `python create_resources.py` to load all resources.) 
I've done some CSV parsing in Python before (including dealing with those ridiculous trailing commas Excel adds (see directly above). If you want to see my code, let me know.
