Fixed authentication issue when username/password has special characters, see issue #62

@bennnjamin Thanks for looking into this, I can confirm this looks like a bug! 👍

Can you update this with a test case to ensure we do not introduce any regressions in the future?

It also looks like this should use rawurldecode(), but this should also be covered by some tests.

You mean to use both rawurlencode() and rawurldecode()? I was not aware of this function but yes it looks like the more correct one. I'm not not sure where to start writing tests. Can you point me to an existing test for logging onto AMI and maybe I can add some additional cases for special usernames and passwords?

@bennnjamin Thanks for looking into this, I've just filed #66 to support authentication with URL-encoded special characters. The code change looks very similar to your suggestion, most of the work was indeed adding some tests to verify this works as expected. Thanks for sparking this idea!
