SpellWeb adds Yahoo! votes

SpellWeb went from scraping all the search engines I could scrape down to the one that gave me a true API to its results: Google. Several weeks ago, I added Alexa results, and now that Yahoo! has opened up their APIs to developers, it was a simple matter to add Yahoo! search results as well, so check it out.

The Yahoo! APIs, use the simple REST web service interface, so the call to Yahoo! is based on an http request with parameters, and parsing the XML file that's returned. For SpellWeb, I'm using a Perl script that uses LWP to make the call and XPATH to read the results.
