#160 Check user email address against smtp host

[Ashley]

This patch adds the ability for the system to check an
email address entered by a user (either at registration
or when editing a profile) against the smtp host
provided in the address, to see if teh host thinks it
is a valid email address.

This functionality is to stop malicious users entering
false email addresses, particularly once registered and
is considered a good preventative step against spammers
and the like.

The attached zip file contains a diff file and three
new files that need to be added under the class directory.

This patch has previously been submitted to xoops.org
as a hack and you can see it working on a 2.2.x site at
http://xoobs.net

This patch was prepared against the 2.3.3 (2.3.0-dev)
trunk.

Ashley Kitson
