Rebuild Named Zone Files

This script will rebuild all your /var/named/*.db files. It first pulls every client from /var/cpanel/users and grabs each users domain and ip address. It then pulls the first 2 nameservers from /etc/wwwacct.conf and rebuilds the zones to how they would be if you just setup this account.
