Not able to extract content

Not able to extract content from the some websites like quora.com and possibly some others.
It is returning 403, for HEAD request method at this line in HtmlFetcher class.

Quora returns 403 for a HEAD request, if you call fetchAndExtract but set resolve to false it will work. I can add a pull request for this, adding an option where if the HEAD request fails it falls back on a GET request.
