... because copy-and-paste is worth discouraging. Moved code that
writes and digests our Q Local XML form of the data into a common
class, localexml.Locale, for use by the scripts that write and read
it. Hopefully, it'll be easier to keep what's written and read in
sync hereafter.
Inlined some trivial functions in the process; and only create a
day-number mapping dictionary once, instead of once per use. Also
made it easier to see which attributes get which special handling (and
documented this); and revised an assertion to be more helpful.
