Define the build timestamp only if given in the environment.

	* acconfig.h:
	* configure.in:
	Define the build timestamp only if given in the environment.

	* libnautilus-extensions/nautilus-file-utilities.c:
	(nautilus_get_build_timestamp):
	* libnautilus-extensions/nautilus-file-utilities.h:
	New function to obtain the build timestamp.

	* src/nautilus-window-manage-views.c:
	(window_set_title_with_timestamp), (update_title):
	* src/nautilus-window-menus.c: (get_about_box_timestamp_string),
	(help_menu_about_nautilus_callback):
	Display the build timestamp in both the about box and window
	title.   This only happens if the build timestamp is set at
	compile time.
