Fix the template modification for changes in newer betas.

This update changes some of the code structure.

It also includes some minor changes to templates to improve the appearance.

There is a new feature, the ability to make the verified user group the primary usergroup as opposed to add it as a secondary user group. This is an advanced feature and generally wouldn't be used.
