introduces the fullAddress field

A new required fullAddress string field has been added to the Address composite.
Type: string, required, max length 318 characters (= 80 + 10 + 10 + 128 + 10 + 80, the sum of the other address field maximums).

In practice the max length should account for an extra dividing character (space) between each field
Probably a rare edge case that all fields are used to the max, but nevertheless.
