All attachments tables should be collapsable

[Jono M]

At the moment, the Attachments section of the Text box blocktype can be collapsed and expanded. It's a good way of simplifying the layout if there are multiple attachments or multiple text boxes with attachments on a page.
Other artefacts (eg. journal entries) can also have attachments, however the boxes showing their attachments cannot be collapsed. It would be nice if they all used the same style and could all be collapsed and expanded. Note that this would require including the resumeshowhide.js file on all relevant pages.
