Title: Fixes some W3C validator issues

Due to the XHTML namespace declaration being present only in chrome.xsl, the W3C validator spits tons of issues related to namespaces.

This patch makes it so that there's only one XHTML declaration at the top of the output, which should in turn fix most such errors. In addition, it also changes the output method to XML, adds a DTD, and adds some "alt" attributes to some "img" elements, which fix a lot of other validator errors.

There are still a lot of other errors, but the fixes for them might be a little more complicated than what was done here.
