Is is possible to add `Access-Control-Allow-Origin: *` header to https://boilerpipe-web.appspot.com/

Hello @kohlschuetter,

Thanks for this awesome project and the service on https://boilerpipe-web.appspot.com/, because its powerful feature, browser extensions like https://github.com/Muffo/fullyfeedly could use it to extract articles from websites, but without Access-Control-Allow-Origin header to allow cross-origin resource sharing, this feature can't really work.

As https://boilerpipe-web.appspot.com/ is a public service, I wonder if it's possible to add the header with value *, so that it can work on many places?

Thank you again!
