#3295 Meta-moderation radio button elements are not labelled

[Simon Lieschke]

The radio button elements for meta-moderating are not
labelled. See
http://diveintoaccessibility.org/day_28_labeling_form_elements.html
for details about labeling form elements.

Doing this enlarges the target area to activate the
radio buttons, and would motivate me to meta-moderate
more often as it would be easier to perform.
