Web design changes, fixes, standards compliance.

One thing I was unsure about was your preference for how to handle external resources. I am using one font that comes directly from Google Web Fonts. Prettify (syntax highlighting library) on the other hand I have pulled into WEBDIR with an svn checkout of the original project when you do `make webpages`. It would be just as easy to reference Prettify from an external server. Would you prefer that all resources are local or is referencing files on external servers ok?
