Title: Change DB to use Active Record conventions

I renamed a number of tables and columns to use Active Record conventions; in most cases, this means simply pluralizing tables and adding _id to columns. Having a worlds table didn't make much sense, so I changed it to countries (which is more descriptive anyway). Addresses issues #50 and #53.
