#3 Improvemnts to attachments GUI and/or documentation

[Virgil]

I've got it working - so please ignore the previous emails.

I had inadvertently deleted $extracted_file_path$ from Attachments (not realizing it's significance).

It obviously uses this in addition to the generated report to create the attachment.

When I read the documentation the 'Attachment' section is written as though it is only used if you want to attach more than one item.

It would be helpful (for people like me) if it was made very clear that the $extracted_file_path$ variable is required under Attachments for the 'out of the box' functionality. I had been playing around with various different things and as I said this got deleted, but without me realizing why it was there.
