=head1 NAME
 UpdatePriority is a ScriptAction that updates the priority of a ticket
 to match that of the queue it is in. UpdatePriority is supposed to be
 called by an RT escalation tool, such as rt-crontool. It makes it
 possible to move a ticket from one queue to another, and have the
 ticket's priority updated.
 Here's an example: Suppose you have tree queues. One where the tickets
 are due in 7 days, one where they are due in 14 days and one where
 they are due in 30 days. If you now wanted to move tickets from one
 queue to another, the due date for the tickets would be wrong. You
 would then run this ScriptAction to update the priority in the moved
 UpdatePriority will change the ticket's priority to satisfy this
 priority =
 (FinalPriority / DefaultDueIn) * (today - Created) + InitialPriority
