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 g_object_ref() on the #WebKitURISchemeRequest and calling webkit_uri_scheme_request_finish() later when the data of the request is available or webkit_uri_scheme_request_finish_error() in case of error.
