www support and domain mapping

Just a fyi in case folks haven't see it. Donncha's domain mapping plugin now supports www.

There's also an option for accessing the backend with either the original url or the mapped one. I;m strongly against that but others may see a need for it.

edit: Wow, all this time and we only have a single Donncha tagged post? That's weird.
