Flush Rewrite Rules code correction

This needs to be fixed. Thanks.

By doing this generalized check for if any plugin saves its settings you wipe out/delete the root .htaccess file code whenever ANY plugin settings are saved. Typically flush rewrite rules should ONLY be used on plugin activation and deactivation. Please correct this. Thank you.

// Init stuff
        function init() {
            if ('true' == @$_REQUEST['settings-updated']) {
                global $wp_rewrite;
				$wp_rewrite->flush_rules();
            }
        }
