Fixed bug 4899 (Bookmark for nonexistent file can cause
	infinite loop at startup)

	Changed NautilusBookmark's internal logic so that it doesn't
	keep around a file object for known non-existent URIs. The
	trick is to get it to notice when the URI is no longer non-existent
	and get a fresh file object then. This is done imperfectly, but
	the new symptom is very minor and deferrable (wrote it up as bug 4906).

	* libnautilus-extensions/nautilus-bookmark.c:
	(nautilus_bookmark_connect_file): Don't get a new NautilusFile
	object if we know the URI doesn't exist; instead just set the
	missing-bookmark icon. Also made it safe to call this routine
	when there's already a file object in hand (just bails out early).
	(nautilus_bookmark_get_icon), (nautilus_bookmark_get_uri):
	Call nautilus_bookmark_connect_file so that it will connect to a
	now-existing file if possible (and thus	get the right icon).
	Since callers that try to activate the bookmark will call get_uri,
	one way to kick a reincarnated bookmark's icon into appearing is
	to select it in a menu.
	(nautilus_bookmark_get_pixbuf): Call nautilus_bookmark_get_icon to
	benefit from its connect_file logic.


	Fixed bug 3847 (Icon in properties window flashes while
	folder count increments)

	* libnautilus-extensions/nautilus-image.c:
	(nautilus_image_set_pixbuf): Don't call gtk_widget_queue_resize if
	the pixbuf hasn't changed.


	Fixed bug 1454 (Properties dialog needs mucho tweaking)

	Mostly this was changes to match Arlo's design that he gave me
	ages ago. I also fixed a few other problems.

	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_get_date_as_string): Change format of date
	strings from "<date> <time>" to "<date> at <time>" to match
	Arlo's design.
	* src/file-manager/fm-properties-window.c:
	(attach_label): Now handles requests for a bold font.
	(attach_value_label): Renamed from attach_left_aligned_label, use bold
	font here.
	(attach_value_field),(attach_directory_contents_value_field):
	updated for name change.
	(attach_right_aligned_label): Removed, guts moved to caller.
	(attach_title_field): Use bold font here.
	(attach_option_menu): New helper function to share code between
	attach_group_menu and attach_owner_menu; now uses gtk_alignment
	to make the menu be minimally-sized and left-aligned.
	(attach_group_menu), (attach_owner_menu): Use attach_option_menu.
	(attach_separator): New helper function to install a separator
	across both columns of a properties window table.
	(create_basic_page): Use gtk_alignment to make the icon right-aligned;
	make the blank row above date rows be standard height.
	(create_emblems_page): Changed layout so name appears below emblem
	rather than to its right; this matches Customize window and allows
	the Properties window to be a smaller width, which looks much better
	for the other panes. Also, the emblems are now layed out lrtb instead of
	tblr.
	(add_permissions_column_label): Make these labels bold.
	(add_special_execution_flags): Attach a separator.
	(get_adjusted_permissions_row): Helper function to account for the "special
	flags" rows, which are not always displayed.
	(create_permissions_page): Deploy get_adjusted_permissions_row wherever a
	raw row number was used; insert separators.
	(create_properties_window): Allow window to be stretched, since the emblems
	don't all fit at initial window height (so user can stretch rather than
	scrolling if desired).
