Add payment collection

This is the same as a payment, but the user is the payee instead of the
payer.

I used a different relation than payment because i do not know any other
way to encode the constraint that only invoices can have a collection,
while expenses have only payments.

Besides the name and the fact that they are related to invoices, a
collection is pretty much the same as a payment.
