Add the option to forbid multiple address per profile

I think having an option on the Address Book which will forbid users to have more than 1 profile per type, makes sense.

What that would change once that option is selected:

• Replace the add / remove address by an edit link (or an add link if no address exists)
• Automatically prefill the existing address in the checkout profile panes (#1799958: First shipping profile ist not being set as default)
• Remove the addressbook select list in the checkout profile panes

Any thoughts ?
