#2 add new ticket hangs at addSubmit.php

[jaquita]

As described in the forum:

When using zenTracksXoops module, whenever I post a new
ticket I get returned to a blank screen. The URL
indicates the addSubmit.php file is being accessed but
processing stops there.

I tracked the problem down to the
includes/zenTrack.class file on lines 3859-3861. This
section tries to set up sending an email even though
the email interface is disabled in zenTrack
configuration. Commenting out these four lines enables
expected behaviour. It seems the problem is probably
elsewhere in the code but this was the quickest and
easiest way to get it fixed.
