Workaround for '$ref' property name.

[IvanGoncharov]

Property could have '$ref' name it's valid name.
Moreover such swagger files exist in the wild see swagger for Google Discovery service.
It would be common problem for any API which return json-schema.
I implement workaround it solve problem but in the same time allowing incorrect references.
I understand that for proper reference detection you need to re-implement half of your library.
In any case it should be addressed in FAQ

@IvanGoncharov, I added some new unit tests specifically for this. Thanks again for reporting the bug.

I also added all 108 of your Swagger files to the test suite, which uncovered a few other bugs. All of those bugs are fixed now as well.

Thank you very much. I didn't expect such quick fix.
I'm very happy that our collection helping other people with their projects.
We will further expand our API collection.
Till the end of March we plan to add Instagram, Github, Stripe, Twitter and many others.
Also API Evangelist promise us to contribute 700+ additional APIs.
If you have Swagger files for any public API(free or paid, including API for devices), please feel free to make pull request.
