AJAX Search API for Beta Blogger

Blogger template hacking-via-javascript:
Notable stuff:
- the sidebar's "Google Search" field searches multiple indexes (Web and BlogSearch), as well as individual sites (in this case the AJAX Search API blog, the Google blog and www.blogger.com) - you can customize all of these things
- the sidebar's "Video Search" field displays (and plays!) results inline
- links in the main blog section can dynamically link directly into the sidebar's embedded Map and Video boxes (try clicking the 'Sakana' and 'Jimi Hendrix' links)
