This patch removes links to jQueryUI assets which are not required in
the self-checkout and self-checkin pages.
The patch also adds missing JS to the self-checkin page related to
internationalization. This prevents a JS error related to an undefined
function, "__".
To test, apply the patch and view the main pages in self-checkout and
self-checkin, and the help page in self checkout. There should be no
errors in the browser console related to missing files.
