WebContext.registerUriScheme

Register scheme in context, so that when an URI request with scheme is made in the #WebKitWebContext, the #WebKitURISchemeRequestCallback registered will be called with a #WebKitURISchemeRequest. It is possible to handle URI scheme requests asynchronously, by calling gobject.object.ObjectWrap.ref_ on the #WebKitURISchemeRequest and calling webkit.urischeme_request.URISchemeRequest.finish later when the data of the request is available or webkit.urischeme_request.URISchemeRequest.finishError in case of error.
