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.

@deadlybutter @aaronschachter Wondering what `$suggestions` vs `$search` is? In what cases would `$suggestions` be true, and what does it print and does it need to be themed like the other results?
