Invoices to email

[yegor256]

Let's make it possible to invoice each other. The user have to be able to click to /invoice and below the invoice text enter three values: the amount, the description, and the email to send to. Then, we send an email. In the email we say that "you are asked to pay for this and that, please click here."

The recipient of the email clicks "Pay" and gets into the /pay page, where all fields are already pre-filled with the right values. All the user has left to do is fill the keygap and click "Pay".
