No way to add a full swagger header in the main html webpage

Add possibility to add an optional full swagger header by referencing a info dict to the docs method. See this commit to deal with this issue: https://github.com/lounagen/flask-restful-swagger/commit/e72ab6616a47dc1b815e55afafb0a2b14d72c582

And here is a screenshot of a sample rendering (sample info content was added as a comment into the docs method comments):

I would also find this very useful.
