* data/build-locationdb.pl: Mark PPLA ("state capital") cities as
	importance 1, not importance 2 (meaning we won't create <city>
	entries for them automatically). Importance=2 worked well for some
	countries, but for most countries it just ends up creating a whole
	lot of cruft.

	* data/update-locations.py: Fix a regexp to not mangle the spacing
	around "/" in some cases.
	(LocBase.__init__, LocBase.print_xml): Handle <timezones> when
	regenerating Locations.xml.in
	(Country.__init__, City.print_xml): Fix the comments on cities to
	insert "the" where needed. (eg, "a city in the United States",
	not "a city in United States").

	* data/Locations.xml.in: Regenerate, dropping 629 cities, changing
	a bunch of comments
