Show Purpose field in customer and vendor contacts

In the current version you need to go to edit contact informtion to be able to see the Purpose.

It will be more useful when you can add this field in the contact area information.

We would liketo add multiple e-mailadresses. 1 for invoicing, 1 for purchase sales order, 1 for credit memo.

Of course one can add this in the description, but a drop down window (like purpose) is more idiot proof.

Especially when you use that code to determine who to email a certain document to.
