OCD Much? Normalizing Your OS X Address Book

While working on another project that will be modifying my OS X Address Book, I happened to notice that all of my phone numbers were being output in a non-standard way on vCards. Rather than dealing with it in subsequent steps, I decided to resolve the issue at the source (in other words, my other project is allowed to be fragile because it is just for me). Solution?

Simple enough. Enjoy!
