"all" in tagmail.conf should allow exclusions

Here's the class I'm using that isn't excluded by "!trim_reports."

class trim_reports {
    tidy { "/var/lib/puppet/reports":
        recurse => true,
        backup  => false,
        type    => ctime,
        age     => '5d';
    }
}

I did some testing and found the class name (trim_reports) does not appear to be picked up as a tag.

  tags:

  - :tidy
  - :ensure

After adding "tag => trim_reports" to the class the tag was picked up and excluded from the email properly.
