Fixing script for "editor unable to save"

Hi Matthew!,

This plugin was a great plugin, but there was a problem when i become an editor level, there is an option page, but i was unable to save the options.

Then i add this script to your plugin, so please update ??
restrict-categories.php on line 331

/**
 * Add editor capability to save the option
 *
 */
$editor = get_role('editor');
$editor->add_cap('edit_theme_options');

add_filter( 'option_page_capability_RestrictCats_options_group', 'RestrictCats_editor_capability' );
add_filter( 'option_page_capability_RestrictCats_user_options_group', 'RestrictCats_editor_capability' );
function RestrictCats_editor_capability( $cap ) {
    return 'edit_theme_options';
}
