Search appearance

This builds on the work @blisteringherb did on getting an image add to each search result and updating the appearance for the main search page. I made some style tweaks based on the mocks and refactored it a little to use the new neue theme functions @aaronschachter and I worked on.

Just checking: Does this throw PHP warnings?  I think it might.  Might be worth doing one last check in the logs to make sure all looks good http://dev.dosomething.org:8888/admin/reports/dblog
