Feature: Make contacts configurable.

[hvorragend]

By default Formicula creates a Webmaster contact from the site admin. This contact becomes contact number one and is first in the drop-down list of "who to contact" in the default contact form even if you add other (more important) contacts.

The only way to make a different contact the default (selected) contact or to order multiple contacts is to change the contact ID numbers in the database directly.

Please consider adding the ability to order contacts by drag and drop so they can easily be placed on the form in the order desired.
