Partner saved search creator is now notified if a user unsubscribes.
Added mysearch messages to opt out notifications.
Made sure email is only sent if email addresses and saved searches exist.
Added partner info to notification and refactored a couple of things.
made a copy of the saved search list so that partner saved searches don't appear in the regular saved search section. Hat tip to @tdphillips
Only show message if contact and partner is unique.
Added space between name and email
