* libnautilus-extensions/nautilus-file.h:
	* libnautilus-extensions/nautilus-file.c: (nautilus_file_rename):
	(nautilus_file_set_permissions): Changed to do both rename and set
	permissions with an interface that will work for async. Also
	improved the handling of deleted files, empty-string names, and
	files you can't change permissions on: they are considering
	runtime errors instead of coding mistakes now. Also send out
	file_changed even if the call fails.

	* src/file-manager/fm-error-reporting.h:
	* src/file-manager/fm-error-reporting.c: (show_error_message_box),
	(fm_report_error_renaming_file),
	(fm_report_error_setting_permissions): Simplified interface to
	these calls. Now we don't require the caller to pass anything we
	can compute ourselves and you can call these with GNOME_VFS_OK
	and they will do nothing. Also merged common code to put up the
	error message box into a helper function.

	* src/file-manager/fm-icon-view.c: (rename_callback),
	(fm_icon_view_icon_text_changed_callback):
	* src/file-manager/fm-properties-window.c: (rename_callback),
	(name_field_done_editing), (permission_change_callback),
	(permissions_check_button_toggled):
	Updated callers to use the new calls.
