Add seeds for the data we need to ship along with the app

What: Add seeds for the data we need to ship along with the app

Why: Right now the app doesn't ship with seed data, and we need this for at least the plans.

How:

We could use https://github.com/mbleigh/seed-fu to handle seeds since is a better way to work with it and are run after database migrations. We can also use what Rails provide but we need to make sure seeds can be run multiple times without duplicating records

This is not necessary, but we still need to have seed data in the app. I'll change the description to reflect this
