[JDEV] More on JUD register function

[Migs Paraz]

Hi,
Thanks to DJ, I have made some progress in my JUD component written in Perl.

The problem for now is how to report the error message if registration failed.

Both of these didn't work - Gabber just said it failed, but showed no error.

SEND: <iq id='A68' to='baloney at localhost/Gabber' from='jud.localhost' type='error'><error>My Error.</error></iq>

SEND: <iq id='A68' to='baloney at localhost/Gabber' from='jud.localhost' type='error'><query xmlns='jabber:iq:register><error>My Error.</error></query></iq>



I'm going to put in DBI database calls, and hopefully this could be a 
teaching example. :)
