	* libnautilus-extensions/nautilus-global-preferences.c:
	* libnautilus-extensions/nautilus-global-preferences.h:
	Add a preference for having the desktop directory point at the
	Unix homedir rather than the default Nautilus desktop directory.

	* libnautilus-extensions/nautilus-file-utilities.c:
	(nautilus_get_desktop_directory):
	Check the preference and return the appropriate directory.

	* src/nautilus-application.c: (nautilus_application_startup),
	(confirm_ok_to_run_as_root), (desktop_location_changed_callback):
	Add a callback for updating the desktop when the preference
	changes.

	* src/nautilus-desktop-window.h:
	* src/nautilus-desktop-window.c:
	(nautilus_desktop_window_update_directory),
	(nautilus_desktop_window_new):
	Add boolean variable affect_desktop_on_next_location_change to
	allow reloading of the desktop dir (rather than loading on open
	in to a new/toplevel window). Add a function for telling the
	desktop window to point to the updated destkop location.

	* src/nautilus-window-manage-views.c: (open_location):
	Check whether this open should be done in the desktop itself or
	if we should open a new window (/ recycle an existing window).
