Data field for address table

The QUIQQER users_adress table needs a data field to save custom data attributes to an address.

This is needed to give context to some addresses. Example: If a users pays via Amazon Pay (QUIQQER ERP stack), Amazon can deliver a shipping adress from the users Amazon account. This address may need to be saved in the address table and somehow marked as an Amazon address.

Likewise, the \QUI\Users\Adress object needs a (simple) API to set custom data.
