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.

@weerd well, what i was running into is that we need the search results on both the 404 and search page, themed the same way, and there was duplicate code that was running through array of results and theming them. So the idea I had for this function was to just have a function I could pass in a set of results to, get the content I need from the result set, and do the theming. 

I agree the naming is weird, it should be more like `paraneue_dosomething_get_search_results_gallery()`.
