Many improvements and fixes to wxUILocale:
- Add wxUILocale method for retrieving wxLocaleIdent identifier,
localized names, layout direction.
- Add wxLocaleIdent attributes, getter, and setter for
platform-dependent tags under Windows: extension, sort order.
- Modify method wxLocaleIdent::FromTag to support not only BCP 47-like
tags, but also platform-dependent syntax.
- Modify method wxLocaleIdent::GetTag to allow specifying the tag type.
- Update internat sample to better show using wxUILocale.
- Update German and French message catalogs for internat sample (German
fully translated, French msgIds only).
- Introduced wxUILocaleImplStdC under Windows, because locale "en-US" is
not equivalent to the C locale.
- Adjust wxLocale class to restore previous wxUILocale in the
destructor.
- Implement wxLocale::GetInfo method through wxUILocale methods.
- Removed LCID dependency in wxLocale.
- Move the implementation of some static wxUILocale methods from
intl.cpp to uilocale.cpp.
