mod_http_muc_log: Tweak style towards the "modern" Also accidentally converted the hand-minified CSS to SCSS for easier editing. This gets rid of the <q> element because it makes browsers (at least Firefox) add annoying quotes to any text copied out of them, interfering with opening non-linkified URLs. That could have been considered a sort of security mechanism, but convenience trumps security!
