From 87fde3f360d557d48241d09cae4f25949e748d4f Mon Sep 17 00:00:00 2001
From: Bharat Mediratta <bharat@menalto.com>

Subject: Create a UI under Admin > Settings > Comments where you can limit
 comments only to registered users.  It's simplistic, but is better than
 adding a permission since generally this setting will be used Gallery-wide.

Fixes ticket #1002
