Reamainders and Remainder email button

[baverhey]

A button on the invoice dashboard for sending reminders for payment. manual
An automated reminder system where you can set a date for all the invoices, say 14 days .(already available or i did that I don't know anymore)

The work flow would be:
5 days before the due date a remainder is sent
On the last day a reminder is sent
2 days after the due date a reminder but different template is sent.

What needs to be done:
So in short a settings page for remainders
with unlimited rows of reminders
each row contains a reminder configuration + or -x due of due date and a template to use.

A general setting for general relative due date +14 days

A possibility to change per invoice due date for the people who want finer control or foreign payment who get more time and so on, or payment plan, extensions and so a lot of use cases when i think of it ;-)

An manual button for sending a remainder, less configuration fits in with the rest of the gui.

I think a lot of the plumbing is already available except the extra fields.
