field filled in, the upload attachment part of the upload form was _above_
the attachment table. Fixed by unsetting new, before array_merge.

- Changed theming of attachment list to use template comment-upload-attachments.tpl.php

Fixed regression: remove notices.

Setting form_state['storage'] in a builder/form_alter leads to immediate rebuilds of the form, which is just too much trouble.

- Added the permission 'view files uploaded to comments'
- Grouped hooks together

- comment form
- user token
- attachment fieldset
