[Plugin: Google Custom Search] Scripts and styles just in front-end

Because the scripts are loaded all over the website, including the administration area on all pages, your plugin conflicts with other plugins ( mainly js errors that prevent other plugins from working ).
Can you please solve the problem? A temporary solution would be to wrap all enqueue functions into an if( !is_admin() ) that will load all files only in front-end.
