Subject: [PATCH] fail to create Monitor section if port-names are not unique
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We should still prevent a user from naming a route "Monitor", but
since "Monitor" is a translatable string, this is an i18n safeguard. eg.
 - create a session with a mon-section and a track Монитор.
 - send the session to a friend in Russia.
