Expand support for XEP-0184.

New stanza interfaces:

    Adding a message receipt request:

        msg['request_receipt'] = True

    Adding a message receipt:

        msg['receipt'] = '123-24234'

    Retrieving the acked message ID:

        ack_id = msg['receipt']
        print(ack_id)
        '123-24234'

New configuration options:

    auto_ack:
        If True, auto reply to messages that request receipts.

        Defaults to True

    auto_request:
        If True, auto add receipt requests to appropriate outgoing
        messages.

        Defaults to False
