Add a dcloud_admin? method to accounts

Segregate organization_id == 1 check into Account instead of checking for in the controller.  This will better position code for when we break apart accounts from organizations.
Editing interface for featured reporting page

Convert the Featured Reporting page to source it's content from the database in markdown format.

To support this:
  * A Backbone editing interface is implemented at /admin/featured
  * Basic CSS to style markdown is included in pages/body.css   This may need to be tweaked to ensure desired styling.  A good test is to paste all the Markdown examples into a report and see how it appears.
  * Since the content is now pulled from the database, I've also added an RSS feed at /featured.rss
