Bug 800402 - [email] UI: Show the number of unread messages in the message-list header after the folder name

typo on hierarchy.  I think I'd go with something like: "The fully qualified path of the folder.  For IMAP servers, this is the raw path including utf-7 encoded parts.  For ActiveSync and POP3 this is just for super-verbose private-data-entraining debugging and testing.  This should be considered private/personal data like the folder name."
