Shiny Upload 'almost' converted into a module

On http://island94.org/articles/overriding you'll find a nice tip + package which enables you to have more user friendly overview of uploaded attachments.

The 'package' on the above page worked out of the box, but gave problems as soon as cron was running.

Attached you'll find a module (+ readme.txt) which does exactly the same thing, but does not break the cron.

Any tips on how I can prevent the 3th step of the installation. (I.e moving the upload_attachments.tpl.php into your theme folder.) are more than welcome.
