OpenID URL parsing creates invalid URLs

[François Marier]

With the following code:

  $avatar_url = $libravatar->url('https://launchpad.net/~fmarier');

the value of $identifier on line 182 ($identifier = $protocol . $identifier;) ends up like this:

  string 'http://https://launchpad.net/~fmarier' (length=37)

which of course throws off the rest of the hashing.
