Fixed bug 4992 ("New folder" menu item enable state doesn't follow
	permissions), bug 4965 (Dragging multiple items to location bar
	crashes Nautilus), and bug 4995 (Rename a file to bad name ->
	error cites wrong filename).

	Fixed a bug jsh spotted where we were doing the mod. time checks
	wrong in the icon factory for thumbnails.

	Did some wording fixes after menthos pointed out some problems.

	* libnautilus-extensions/nautilus-icon-factory.c:
	(get_cache_time): Split out this function to get the mtime of a
	file so we can check when it changed.
	(load_specific_icon): Get the time when loading an icon.
	(scale_icon): Copy the time when making a scaled icon from an
	existing icon.
	(remove_icons_if_file_changed): New renamed function uses
	get_cache_time to check if the icon needs recomputing because of a
	change in the underlying file.
	(get_icon_from_cache): Call the new remove_icons_if_file_changed.
	(load_icon_with_embedded_text): Copy the time when making an icon
	with text from an existing icon.

	* libnautilus-extensions/nautilus-file-attributes.h: Added
	ATTRIBUTE_CAPABILITIES (and sorted in alphabetical order).
	* libnautilus-extensions/nautilus-directory-async.c:
	(nautilus_directory_set_up_request): Changed the name of this,
	made it public, and added ATTRIBUTE_CAPABILITIES as another
	way to ask for the file info.
	(cancel_loading_attributes),
	(nautilus_directory_cancel_loading_file_attributes): Set up a
	request and use it to decide what to cancel.
	* libnautilus-extensions/nautilus-directory-private.h: Moved the
	request structure and call into here so it can be used by
	NautilusFile and NautilusDirectory both.
	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_forget_attributes_internal): Set up a request and
	use it to decide what to forget.
	(nautilus_file_forget_all_attributes): Add ATTRIBUTE_CAPABILITIES
	to the set of things in "all".

	* src/file-manager/fm-directory-view.c:
	(check_for_directory_hard_limit): Added a FIXME and made some
	minor wording improvements.
	(file_changed_callback): Helper to schedule a menu update when
	the directory's NautilusFile reports a change.
	(load_directory): Add monitoring of the directory's "capabilities"
	since they affect whether "New Folder" is allowed. Fixes 4992.
	(disconnect_handler): Helper for the two functions below.
	(disconnect_directory_handler): Disconnect a NautilusDirectory
	handler.
	(disconnect_directory_as_file_handler): Disconnect a NautilusFile
	handler.
	(disconnect_model_handlers): Add code to stop monitoring the
	directory's "capabilities".

	* src/file-manager/fm-error-reporting.c:
	(fm_report_error_renaming_file): Got rid of some unneeded "\n"
	characters. Improved the error message in the "/"-forbidden case
	with a specific special case message and the proper file name (was
	using the old file name, not the new one). Fixes 4995.
	(fm_rename_file): Added quotes to message.

	* src/nautilus-location-bar.h: Removed unused fields.
	* src/nautilus-location-bar.c: (nautilus_location_bar_get_window):
	Find the window by looking for an ancestor instead of trying to
	use gtk_object_get_data (on data no one was setting any
	more!). Fixes 4965.
	(nautilus_location_bar_initialize): Got rid of redundant
	initialization to NULL.
	(nautilus_location_bar_set_location): Got rid of gratuitous check
	before calling g_free.
	(nautilus_location_bar_update_label): Added a localization-related
	FIXME here.

	* libnautilus-extensions/nautilus-file-operations.c:
	(handle_xfer_vfs_error): Corrected the "it's" to "its" even though
	I know that John and Pavel were writing an improved version of the
	entire message.

	* libnautilus-extensions/nautilus-search-uri.c:
	(get_translated_criterion), (nautilus_self_check_search_uri): Say
	"folder" instead of "directory".
	* src/nautilus-search-bar-criterion.c: Say "folder" instead of
	"directory".
	* src/nautilus-theme-selector.c: (add_theme_to_icons): Say
	"folder" instead of "directory". Other minor wording improvements.
	(make_theme_description): Minor wording improvement.

	* src/nautilus-window-manage-views.c:
	(window_set_title_with_timestamp): Added a FIXME.
