Changes since Webmin version 3.19

Virtualmin Virtual Servers (GPL)
When email is set to a new or modified mailbox, the From: address is that of the domain owner.
Fixed a bug that prevented DNS zones from being added to a file other than named.conf, even if specified in the BIND module.
Sub-domains with DNS enabled are now added by default as records in the parent DNS zone, rather than as a completely new zone.
The server template editing page is now broken down into sections, selectable using a menu. This reduces the size of the form, and makes it easier to find settings that you are interested in.
Removed un-needed code to support versions of Webmin below 1.290.
Added missing view_domain.cgi script.
Improved support for running within a Solaris zone (thanks to Textdrive).
Fixed a bug that could cause users in the wrong domain to be deleted when removing a virtual server.
Added an option on the Backup Virtual Servers page to have each server's backup file transfered by SCP or FTP after it is created, rather than doing them all at the end of the backup. This saves on temporary local disk space on the server running Virtualmin.
Added the delete-domain.pl script (ported from the Pro version).
Virtusers associated with mailboxes are not un-necessarily removed and re-added when no email related changes are made.
