Clearer search results, working filters and feeds

Small fixes that make the site easier to find and use.

• Page titles show in full in search results, instead of being cut off
• Finds and Releases have clearer headings
• Filter and sort links work on every page of Finds, not just the first
• Our RSS feeds list the latest finds and articles
• Photos describe where they were taken, for people using screen readers

Example: a Google result for a find now shows the shoe and its price in full, instead of a title cut off halfway.
