Happy holidays!

This PR adds the workaround to avoid GoogleAuthentication's bug (fix #94).
Please review it when you got time.

Thinking twice, I think I should put the how-to on the wiki rather than adding an optional function to the package. Because the problem itself is not caused by our package, but by GoogleAuthenticator itself.

What do you think? --> @pquerna

@KEINOS just having the information is a little underwhelming since adapting will involve parsing and reassembling the url. this package is about otp and the google authenticator has a central role in the otp universe, whether we like it or not.

for some strange reason, this package started mangling the query parameters, pushing the secret to the back and exposing that strange behaviour of the google authenticator. forcing all users of the package to sift through the query parameters yet again is not a good solution.
