Provide the ability to sort email addresses, alphabetically or otherwise, within the active edit invoice view.

Example, when editing an invoice you can scroll down and see all the emails associated to the company, below. They are not sorted, instead they display from left to right, and top to bottom like reading a book, starting from the most recently added contact.

It would be great to be able to sort alphabetically, or drag them around in order of importance or some way to sort, usefully.
