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.

@aaronschachter Good to know. I will fix.
