[documentation] Touch-hold .prevent.stop

[mesqueeb]

In the Touch-hold documentation at the bottom: API

At "modifiers" it only says mouse, but if we're able to use .prevent.stop as well, I think it might be really helpful if they are listed there as well!

If we are NOT able to use .prevent.stop, i'd love to ask this to be added as a new feature.

If we add prevent and stop then user won't be able to select text. It's pretty complicated to explain all the reasoning (takes pages), but regardless, if you need it you can evt.preventDefault() and evt.stopPropagation() yourself in the handler, at the right time.
