Add agi::Color, and replace AssColor and all uses of wxColor that are not immediately passed to/from wx with it.
Use wxTranslations directly rather than going through wxLocale. This significantly simplifies the code, eliminates the hardcoded list of languages for non-windows, and makes it possible to use mismatched languages and locales. Closes #1508.
