jQuery UI Touch Punch disabled

[Andrey Novoseltsev]

As it was causing troubles with new jQuery shipped with Sage 8.5, jQuery UI Touch Punch is disabled on public servers.

If you are aware of any use cases for it - please test whether they are working without it or are broken. (I have no idea what it was supposed to be doing for SageMathCell.)

It was introduced to allow the interact sliders to work on mobile devices. IIRC, the jqueryui sliders used in interacts *still* don't respond to touch events, so don't work on mobile devices. There may be other controls that don't work with touch events as well. Jquery UI Touch Punch converts touch events to mouse events (IIRC), so that sliders work with mobile devices.

We have the same problem with ipywidgets - our sliders also don't react to touch events. We've thought about moving to something like nouislider or a react-based slider (see https://github.com/jupyter-widgets/ipywidgets/issues/630).

Thanks,

Jason
