Title: Send automatic payment reminders

It would be nice to alert people some time before the event when they haven't paid yet. E.g. automatically send an e-mail 7 and 4 days before the event to remind them that the option to pay online is almost closed.

Preferably make this option configurable.

Extra: allow to set multiple reminders.
