Reservation Bucketing

[orenyk]

Requested by UP:

The student and the admin currently recieve one email per item checked out and students are often checking out packages of gear, all due at the same time. It would be awesome to recieve all of this info in one email, like when you order 3 things from amazon or check out 3 books from the library.

Our one-reservation-per-equipment-model rule definitely makes the coding easier on the back end, but we might want to consider implementing an Order class (or something along those lines) for groups of simultaneous reservations. Adding to the wish list for now.
