Weather in XML format

For quite some time we've ben using the XML Weather servcies of Boy Genius.

In preparation for some XSL work, we're now running the same Perl script that he runs, and keeping the data ourself.

Feel free to use it all you want (a nice plug stating where you're getting the data from would be nice though). The data is updated every 3 hours, so there's no point in updating from the feeds more often than that.
