* check-strings.pl:
	* check-strings-functions:
	* check-strings-patterns:
	New script and correspoinding config files to help us find
	untranslated strings. It's going to take some effort to make
	this an easy-to-use tool.

	* components/rpmview/nautilus-rpm-view.c:
	(nautilus_rpm_view_initialize): Fixed string that would not
	get translated properly since it was using N_ and nothing
	was going to use _() on it.
	(nautilus_rpm_view_update_from_uri): Marked strings for
	translation as requested in bug report 7149.
	(nautilus_rpm_view_verify_files): Format tweak.
	(nautilus_rpm_view_drag_data_received): Remove old dead code.

	* libnautilus-extensions/nautilus-tabs.c: (draw_tab_piece_aa):
	Change to use C-style comments, not C++.

	* src/nautilus-application.c: (check_required_directories): Mark
	strings for translation that we had missed before.
	* src/nautilus-first-time-druid.c: Fix port string define so it
	doesn't have to be repeated twice (and doesn't show up as an
	"untranslated string").

	* src/nautilus-about.c: Formatting tweak.
	* src/nautilus-location-bar.c: Fix typo.
