Parts Reservation Send Message to Mechanic

Would like to see more robustness in the Parts Reservation module. On top of the idea in “Parts Reservation should send messages to parts clerk”, Add a pop up when reserving parts if there are parts on hand for the mechanic. Also, adding either a RTA Messenger notification, or external email notification when reservations are received. This would tell the mechanic that his parts are in and he can finish the job.
