	No more overlapping desktop icons.

	Implement a layout timestamp concept where each file on the desktop
	and the desktop directory itself is timestamped when a full layout
	happened. Iff files were not part of the last layout (or added more
	recently, through DND), they are treated as being “semi-positioned“
	(cf. 2005-11-07).
	This means that they may be freely shifted around, starting from their
	last position, until they don't overlap and fully laid out items.
	Should inter alia fix #330298.
