Domain mapping

Allows multiple domains to map to your blog

#1 lets blogs be created on multiple domains, like myblog.yourpress.com and myblog.ourpress.com

#2 runs full domains off the same WordPress installation, like myblog.com and yourblog.com

#3 does the same as #2, but also supports cnames (so if your main site's IP ever changes, your users don't have to update DNS records) but is a little harder to setup and maintain
