Updated site to scale better on small screens; Added clearfix css; Updated shadow feature to use css shadows instead of js/images.

Added code to the admin part of the site - still non-functional.  Need to fix JSON streaming over HTTP such that native types (boolean, Date, int) are preserved for the DB;  Need to finish the restore functionality & the hide/show of the edit, delete, and restore buttons on each editor page.
