Split mailing label formatting out from main format

[eileenmcnaughton]

Overview

Splitting these 2 functions out allows cleanup & eventual decommissioning of the mailing label
function.

There are siginificant usage differences depending on context so this will permit
cleanup - I did a universe search & these are the only 2 times it is called with
mailing = TRUE

Before

One big toxic function does a whole lotta stuff

After

We've started the separation & cleanup
