ADDED PAGE PART EDITING:

You can now add page parts when editing Pages in the backend. there's a +/- symbol on the top right that allows you to add/remove page parts. the name you give it will be it's CSS ID. For everything else we can override views by exposing their partials. this can be done in the terminal w/ rake refinery:override view=YOUR_TARGET_VIEW. the page part was change in app/config/initializers/refinery/pages.rb
