Support for delayed filling-in of storages/folders.

	* Evolution-Storage.idl (StorageListener): add
	notifyHasSubfolders, to announce that a folder has currently-
	unknown subfolders.
	(Storage): add asyncOpenFolder, to request that previously-
	announced subfolders be filled in.

	* evolution-storage.c (impl_Storage_async_open_folder): emit
	OPEN_FOLDER.
	(evolution_storage_has_subfolders): Implement by calling
	notifyHasSubfolders on all of its listeners.

	* evolution-storage-listener.c
	(impl_GNOME_Evolution_StorageListener_notifyHasSubfolders): emit
	HAS_SUBFOLDERS.

	* e-corba-storage.c (impl_StorageListener_notifyHasSubfolders):
	Implement by calling e_storage_has_subfolders.
	(async_open_folder): Implement by calling asyncOpenFolder on the
	CORBA storage.

	* e-storage.c (EStoragePrivate, init, destroy): Keep a list of
	pseudofolders representing un-filled-in subtrees.
	(impl_async_open_folder): No-op default implementation
	(e_storage_async_open_folder): New function to request that
	un-filled-in subtrees be filled in.
	(e_storage_new_folder): If the new folder's parent has an
	"un-filled-in children" pseudofolder, remove it.
	(e_storage_has_subfolders): New function to note that a folder has
	unknown children. If the folder previously was marked as having
	real children, remove them, and emit CLOSE_FOLDER to reset it back
	to an a "unknown subfolders" state.

	* e-storage-set.c (make_full_path): Make this deal with path being
	"/", since that case gets used from storage_close_folder_cb
	sometimes.
	(storage_close_folder_cb): Proxy EStorage's CLOSE_FOLDER signal.
	(storage_set_view_folder_opened): Handle EStorageSetView's
	FOLDER_OPENED signal by calling e_storage_async_open_folder.

	* e-storage-set-view.c (etree_fill_in_children): If the given node
	is its parent's first child, emit FOLDER_OPENED for the parent.
	(close_folder_cb): Handler for EStorageSet's CLOSE_FOLDER signal.
	Ask the model to close that node.
	(e_storage_set_view_construct): Set the default expanded state for
	the tree to FALSE rather than TRUE, to prevent unwanted expansion
	of delayed nodes. (This only affects the very first time the tree
	is displayed anyway: after that its state is loaded off disk.)

	* e-shell.c (e_shell_construct): Register the "noselect" type with
	the folder type registry, so icon lookups on placeholder folders
	will work.
