exp/locale/collate: changed API to allow access to different locales through New(),
instead of variables. Several reasons: - Encourage users of the API to minimize the number of creations and reuse Collate objects. - Don't rule out the possibility of using initialization code for collators. For some locales it will be possible to have very compact representations that can be quickly expanded into a proper table on demand. Other changes: - Change name of root* vars to main*, as the tables are shared between locales. - Added Locales() method to get a list of supported locales.
