Append HMI Web 1.8.1

Fixed

A touch now reaches the object underneath. In a browser as on the desktop,
an object placed over one with a touch animation swallowed the operator's
touch, so a label or a panel drawn over a button stopped it from ever being
pressed. A touch now goes to the topmost object that has a touch animation,
anything over it with none is seen through, and the pointing hand shows there
too. A touch animation on a group works for the first time.

Carries Append HMI Studio 1.7.1, which brings the fix. See the Studio release
notes for the details.
