Bug 5191 Patron notification was being reset to none

Bug 5191 Patron notification was being reset to none

The value of the letter variable was not being correctly passed
to the edit template instead it was reset to none
Also compressed some verbage from letter_loop generation
(if you want a scalar use one)
removed an unused $count variable (?!)
and put a couple of lone )s back on the line they came from

Resend to remove wrong utf-9 header.
