Make anonymous comments clearer in alert emails

[chrismytton]

When showing a list of comments in HTML emails we previously didn't show anything for updates that were left anonymously. This led to some confusion about which text related to which update.

This change means that anonymous comments will show the text "Posted anonymously" next to them, which should make things a bit clearer.

Manually testing this was a bit awkward. I ended up changing this line to have item_anonymous => 1 so all updates appeared as anonymous on /_dev/email/alert-update. There may be a better way!

item_name => $u->name, item_anonymous => $u->anonymous, confirmed => $u->confirmed };

Nice and neat. Agreed that it's a bit awkward to test manually. I guess you could have the $q on L106 fetch updates from the report being displayed and fallback to the existing behaviour if there weren't any.

@davea This works really well, thanks! I've added an extra commit to the end of this PR which does this, would you mind taking a look?

[davea]

Looks good! :)
