... 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.
