Duplicate phrase detection

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/78a99ec279bd9f1e#

I propose we tell admin (during phrase adding/editing), what other phrases in language pack have same translation as it's phrase. In most cases duplicate translation will mean nothing, but sometimes it will help to prevent duplicate translations.
