Reloading is broken by latest pull request #52

[ColmHally]

If you're exploring an API and try to reload, the page fails to load due to a JSON error:

Uncaught SyntaxError: Unexpected token < in JSON at position 0

This is because the code added in #52 blindly appends on /swagger.json to the current URL, which might be something like http://localhost:8000/#!/pet/updatePet; giving http://localhost:8000/#!/pet/updatePet/swagger.json.

A server seeing this URL will actually just return the index.html page which is not valid JSON.
