 The rules for allowed characters in a site address differ between when you
 add a new site and when you edit an existing site.

 Steps to reproduce:

  1. Go to Network Admin -> Sites -> Add New
  2. Enter `foo.bar` as the site address and hit save. The address will be
 rejected as containing invalid characters.
  3. Edit an existing site instead, and enter `foo.bar.yourdomain.com` as
 the domain. The address will be accepted just fine.

 Having written that out, maybe this isn't a valid bug because when adding
 a site you're entering the site address, but when you're editing a site
 you're editing the complete domain name. Hmm. I'll open it anyway and see
 what people think.

 My core issue is that I'd like to be able to add sites that use fourth-
 level subdomains (eg `foo.bar.baz.com` when the main site is at
 `baz.com`). Currently I have to enter a different site address then go in
 and edit it to the desired domain.
