	Fixes bug #322957:

	Add a "Network Servers" icon on the desktop, which takes you to network:///

	* libnautilus-private/nautilus-global-preferences.h
	(NAUTILUS_PREFERENCES_DESKTOP_NETWORK_VISIBLE): New preference
	name.  This determines whether we show the "Network Servers" icon.

	* libnautilus-private/apps_nautilus_preferences.schemas.in: Add a
	schema for /apps/nautilus/desktop/network_visible; the default is true.

	* libnautilus-private/nautilus-desktop-link.h
	(NautilusDesktopLinkType): Add a NAUTILUS_DESKTOP_LINK_NETWORK type.

	* libnautilus-private/nautilus-desktop-link.c
	(nautilus_desktop_link_new): Support NAUTILUS_DESKTOP_LINK_NETWORK.

	* libnautilus-private/nautilus-desktop-link-monitor.c
	(NautilusDesktopLinkMonitorDetails): Added a network_link field.
	(nautilus_desktop_link_monitor_delete_link): Don't delete
	NAUTILUS_DESKTOP_LINK_NETWORK links.
	(update_link_visibility): New helper function.
	(desktop_home_visible_changed): Use update_link_visibility(), to
	avoid duplicated code.
	(desktop_computer_visible_changed): Likewise.
	(desktop_trash_visible_changed): Likewise.
	(desktop_network_visible_changed): New function.
	(create_link_and_add_preference): New helper function.
	(nautilus_desktop_link_monitor_init): Use
	create_link_and_add_preference() to avoid duplicated code.  Also,
	create the network_link.
	(desktop_link_monitor_finalize): Unref the network_link.
	(remove_link_and_preference): New helper function.
	(desktop_link_monitor_finalize): Use remove_link_and_preference()
	to avoid duplicated code.  Also, free the network_link.

	* src/file-manager/fm-icon-container.c (SortCategory): Add a
	SORT_NETWORK_LINK category right before SORT_MOUNT_LINK, so that
	the "Network Servers" icon appears before mounts.
	(get_sort_category): Use SORT_NETWORK_LINK as the category for
	NAUTILUS_DESKTOP_LINK_NETWORK.
