Admin can change the status of a content item to pending, published, or discarded
- Add status column to the model
- Update the api endpoint to take a status parameter, defaulting to published on GETs
- Add bootstrap.js for button groups
- Add status button groups for each content item and update view to save on change
- Add new navbar items to navigate to each status type
- Update items template to take a status parameter, defaulting to pending
- Move js from items.js to the template so we can easily use the query string param for fetching
- Add Handlebars helpers for checking the status
