Add support for latest version of jQuery UI (v1.13.2). This is used when $config->debug = 'dev'; in /site/config.php. Expect occasional JS/output issues when using this latest version of jQuery UI. We'll be upgrading the default core version to this over a period of time, which is why it's only used if $config->debug=='dev'; at present.
