CORS headers not sent on OPTIONS request

[manutenfruits]

When accessing the shiva-server from a different address or port using AJAX from chrome (after enabling CORS on shiva, of course), the browser first makes a preflight request, using the OPTIONS method.
I've tried with curl and although I can see the Access-Control-Allow-Origin: * on GET request, the OPTIONS request doesn't return that header, so I can't make a single request from Chrome due to this issue.

Sorry for taking so long to address this issue, but finally here is a PR to fix it: #85 Please test and approve.

This seems to be caused by an issue in Flask-RESTful, which I already reported: flask-restful/flask-restful#93

Thanks for the report!

Fixed by #85.
