iconGrid: Add moveItem

Browse source 
This new public API moves items without removing and readding
them, which allows us to avoid some tricky behavior. Noticeably,
following the original design described at 3555550d5, the new
IconGridLayout.moveItem() method does not call `layout_changed`.
This is done by IconGrid itself, queueing a relayout.
