Make Donor Address Required

/**

 * Make all address fields required.

 *

 * As of Charitable 1.6 the approach below is the recommended way of achieving this.

 * If you are using an older version of Charitable, see the legacy version below:

 *

 * @see https://github.com/Charitable/library/blob/master/donation-form/legacy/make-donor-address-required.php

 *

 * @return void
