Fix for blank comments in 4.5.17

[Gwilym (Interspire Staff)]

On some systems, new comments code introduced in 4.5.17 will cause the contents of comments to display as empty. This will be fixed in 4.5.18.

For an immediate fix, a new version of /admin/includes/classes/class.helper.php is attached to this post which corrects the issue and may be applied to your site.
