Title: Adds a block-based interface for the ABPeoplePickerNavigationController

As much fun as that class is to type... ;-)

```ruby
AddressBook.pick { |person|
puts person.inspect
}
```

`person` will be `nil` or an instance of `AddressBook::Person`

Uses the `AddressBook::Picker` class, which stores a singleton reference to itself and assigns itself as a delegate to an instance of `ABPeoplePickerNavigationController`.
