Client Contact Addresses; via the Business Layer you may add an Address with both Postal and Physical unchecked

Using the Business Layer, Client Contact Addresses may be added with both Postal and Physical options unchecked. A check has now been added to stop this.

Note, by default a new Address will now have both Physical and Postal options checked.

In addition, check your script does not directly set the ContactMethodId property, rather it uses the ContactMethodIdSet method. Instead of using ClientContactAddress.ContactMethodId="AD" you should use ClientContactAddress.ContactMethodIdSet("AD").
