	Fixed bug 4717, Nautilus draw desktop icons overlapping.

	The problem was caused by the icon container responding to
	an idle function that lays out icons that had been
	newly added.  This is a problem if the callback is called
	form an idle after th eicon container has been created, but
	before a size has been allocated. A nely intialized GtkWidget
	has a default allocation of 0, 0, 1, 1 which is too small
	for the layout algorithm to work properly.  A flag was added
	that is set to TRUE when the size_allocate function is called.

	* src/nautilus-desktop-window.c: (nautilus_desktop_window_new):
	Set has_been_allocated to FALSE initially.

	* libnautilus-extensions/nautilus-icon-container.c:
	(size_allocate), (nautilus_icon_container_initialize),
	(nautilus_icon_container_add):
	Checj status of has_been_allocated flag before adding
	and laying out new icons.

	* libnautilus-extensions/nautilus-icon-private.h:
	Added has_been_allocated flag that is set to TRUE
	when size_allocated is first called.

	Work in progress on allowing desktop links to be renamed.

	* src/file-manager/fm-desktop-icon-view.c:
	(find_and_update_home_link):
	Allow renaming of home links.

	* src/file-manager/fm-icon-view.c:
	(special_link_in_selection):
	Removed home link from special link types.

	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_can_rename):
	Allow renaming of home link types.
