Title: Add functions to work with retrieving products

This is more handy for digital products, where you need to be able to
get the list of the products you've already purchased to avoid
purchasing them again.

I've placed these at the bottom of `misc.functions.php`, but there may be somewhere that seems more appropriate than there.
