Title: Allow globally setting API user and key

This is a pretty common thing with other APIs I've used... then with Rails you just drop a file into config/initializers to do the onetime setup... then you can use the API anywhere in your app without having to pass it username and password. Of course this isn't exclusive to Rails.
