Mobile/Touch Support

[parsagholipour]

I tried this according to this doc:

import { DndProvider } from 'react-dnd'
import { TouchBackend } from 'react-dnd-touch-backend'

<DndProvider backend={TouchBackend}>
    <SortableTreeWithoutDndContext ... />
</DndProvider>

but didn't work.
I realized SortableTreeWithoutDndContext renders like SortableTree without any wrapping dnd context.

My fork does not support react-dnd-touch-backend. Maybe someday it will be implemented.
