code to load a directory was accidentally waiting for all the
	files to be read in before displaying anything. This fixes the two
	problems that caused that, but there are remaining loose ends
	(it's not entirely clear why View As Music is still showing
	properly in the View menu).

	* libnautilus-private/nautilus-directory-private.h:
	* libnautilus-private/nautilus-directory-async.c:
	(nautilus_directory_call_when_ready_internal): Take a parameter to
	say whether to wait for all the files in the file list, instead of
	deducing it from other parameters.

	* libnautilus-private/nautilus-directory.h:
	* libnautilus-private/nautilus-directory.c:
	(nautilus_directory_call_when_ready): Take a parameter to say
	whether to wait for all the files in the file list, instead of
	deducing it from other parameters.
	(nautilus_self_check_directory): Pass TRUE so we wait for the file
	list.

	* libnautilus-private/nautilus-merged-directory.c:
	(merged_call_when_ready): Pass through the new boolean.
	* libnautilus-private/nautilus-trash-file.c:
	(real_call_when_ready): Pass FALSE since there is no file list for
	a single file.
	* libnautilus-private/nautilus-vfs-directory.c:
	(vfs_call_when_ready): Pass through the new boolean.
	* libnautilus-private/nautilus-vfs-file.c:
	(vfs_file_call_when_ready): Pass FALSE since there is no file list
	for a single file.

	* src/nautilus-applicable-views.c:
	(nautilus_determine_initial_view),
	(nautilus_determine_initial_view_cancel): Removed the code to get
	full file attributes after getting the minimum required if
	nautilus_mime_actions_file_needs_full_file_attributes return
	TRUE. We want to make the choice fast, and it's OK if we choose
	poorly as a result. The question is whether this will cause any
	real end-user problems.

	* src/file-manager/fm-directory-view.c:
	(call_when_ready_on_scripts_directory): Pass TRUE so we read the
	entire scripts directory.
	(load_directory): Pass FALSE so we don't wait for all the files to
	be loaded before starting to display them. This is the core of the
	fix.

	* components/tree/nautilus-tree-change-queue.c:
	(nautilus_tree_change_queue_enqueue): A place where we can use
	g_slist_prepend instead of g_slist_append.
	* src/nautilus-complex-search-bar.c:
	(nautilus_complex_search_bar_initialize): A place where we can use
	g_slist_prepend instead of g_slist_append.
