void webkit_script_dialog_close ( WebKitScriptDialog* dialog )
When handling a
WebKitScriptDialog asynchronously (webkit_script_dialog_ref()
was called in
WebKitWebView::script-dialog callback), this function needs to be called to notify
that we are done with the script dialog. The dialog will be closed on destruction if this function
hasn’t been called before.
