Drag sorting not working on iOS devices

Here’s is a video of what happens

Apparently iOS needs the 'group' option parameter to be defined in the Sortable in order for it to work properly. Attached is a small patch that uses the container's id as the group name for the Sortable widget.

see: https://github.com/SortableJS/Sortable#group-option

This got it working for me.

@loze is this still an issue? Or maybe a (fixed) bug in Sortable.js?
