Small tools update

I've added some small updates to the site. Now you can add the latest SoarPort feeds to your iGoogle account, accessible in the tools section on the main page. Also, there is an Alexa rank image. This is experiemental. We'll see how this goes, if there is any discernable benefit to including this. Finally, some plumbing changes: meta tags are out, and opensearchdescription.xml is in. This was done to improve search results, and we'll have to wait and see if there is a benefit to doing this.
