taking action on lost gl_ES messages (http://openacs.org/forums/message-view?message_id=133859). The messages had ended up in message files with locale utf-8 (don't know why yet). Moving the messages back to ISO-8859-1 files and removing the utf-8 files
removing I18N messages no longer used (almost 200). Collapsing certain keys to make translation easier. Our message key structure is still too fragmented in many places (we have too many keys)
