Add <dfn> To UCP Attachments List Download Count

Probably not classed as a bug but the 'post count' 'reply count' 'reply count' 'view count' on the forum and topic lists have a <dfn> before them for screen readers etc.

Would adding one to the download count be beneficial to screen readers?

File:

ucp_attachments.html

Find:

<dd class="extra">{attachrow.DOWNLOAD_COUNT}</dd>

Change To:

<dd class="extra"><dfn>{L_DOWNLOADS}</dfn>{attachrow.DOWNLOAD_COUNT}</dd>
