Fix issue WP-API/OAuth1#59, OAuth callback isn't called

I had an issue with this. I had to do a rawurldecode() on the callback before saving it to make this work.
However, I agree that this needs to be stored between the request and authorization, otherwise the callback isn't redirected to after successful authorization.

Hmm, indeed, I think this patch applied by itself is insufficient to get the callback working. I also had some issues with double-encoding of the oauth_callback parameter value. Applied #65 and then removed the two rawurlencode() calls in join_with_equals_sign() and was good to go. The url decoding stuff all seems to happen earlier in normalize_parameters()

[coderkevin]

In my case, normalize_parameters() is really messing up my already partially encoded parameters, so by removing normalize_parameters() instead, I was able to keep the rawurldecode() calls.

See: #91

I have created a PR which merges your changes with AlexC's and removes normalize_parameters() in favor of encoding them in the join_with_equals_sign() function: #92

Thanks for the PR!

This is already applied in a separate spot; is this not working for you?

[rmccue]

Closing out; this should be fixed, and in any case, this PR no longer applies as a lot of the code has been rewritten. Thanks anyway!
