Address multi select

[Scribbler2099]

For addresses, instead of having to re-fill the boxes multiple times, for 'work' 'home' 'mailing' 'billing', etc, it would be great if we could use a multi-select thing to fill out the address once, and then select what we're using that address for.  for example, someone might use the same address for 'home' and 'billing' but might want a different address for 'mailing'.  or a different member might want their 'mailing' address to be their 'publicly listed' address, but it won't be their 'home' or 'billing' address.
