{assign} bug fixed

One useful purpose of the fetch method is to send an email based on a template. While documenting an example of this, I discovered that the {assign} tag couldn't handle variables in the value element:

{assign var="to" value="$to_firstname $to_lastname <$to_email>"}

I suppose you could call it a "new feature," but Smarty could do this already, so I'll just call this a bug fix.

If you'd like to ensure you get all emails, use the default modifier:

{assign var="to" value="$to_firstname $to_lastname <$to_email|default:'your.email@organization.com'>"}

Anyway, I'll now continue documenting how to use Dermis to send an email based on a template file.
