[Plugin: Links shortcode] Improved handling of link_updated

This brief snippet will cause the link_updated field to be blank, and thus suppressed by the [optional ...||...] code, if it contains the default of '0000-00-00 00:00:00' — add the lines marked by + (after line 107, the first one shown):

$linkinfo['link_updated'] = $bm->link_updated;
+               if (preg_match('#^[\-0 :]*$#', $linkinfo['link_updated'])) {
+                 $linkinfo['link_updated'] = '';
+               }
                $linkinfo['link_rel'] = $bm->link_rel;

The above is particularly useful with “Andy’s Link Last Edited Meta Box” as described at http://fleacircusdir.livejournal.com/5498.html … which updates WordPress’s link_updated field whenever a link is created or modified. (WP allegedly reserves that field for some other sort of magic which never seems to happen. We might as well use it!)
