Creates a site.

This function runs when a user self-registers a new site as well as when a Super Admin creates a new site. Hook to {@see 'wpmu_new_blog'} for events that should affect all new sites. On subdirectory installations, $domain is the same as the main site's domain, and the path is the subdirectory name (eg 'example.com' and '/blog1/'). On subdomain installations, $domain is the new subdomain + root domain (eg 'blog1.example.com'), and $path is '/'.
