[det]http_set_authorization(+URL, +Authorization)

Set user/password to supply with URLs that have URL as prefix. If Authorization is the atom -, possibly defined authorization is cleared. For example:

?- http_set_authorization('http://www.example.com/private/',
                          basic('John', 'Secret'))

To be done: Move to a separate module, so http_get/3, etc. can use this too.
