Registration email is not being sent.

The D5 code available in the issue queue has not been completely upgraded from 4.7, and the email part of the code is quite messy and doesn't work. I need to do a better account registration and notification function for this. Instead of creating 'from scratch', it's my intention to do using current drupal functionality, submitting the user_save function (not the db_query approach) and that would allow firing the user notification.

This will clean that part of the code so we can integrate in D6 branch easily.
