v0.6.6

Added

• Localization. Twelve languages — en, ru, tk, de, fr, es, zh, ja, tr, pt, ar,
  he — through SeedLocalizations and an ordinary LocalizationsDelegate, so
  the kit follows the app's locale and changes with it at runtime. That is what
  makes it work with intl, easy_localization, slang and the rest while
  depending on none of them: they all set the app's Locale, which is all the
  delegate reads.

  ConfigProvider(locale:) overrides the delegate for a subtree, and
  copyWith replaces a single word without forking a language. A widget
  property still beats both, and with nothing wired up at all the words fall
  back to English rather than throwing — a widget kit has to draw in any
  application.

  Every word but noMoreItems is taken from Ant Design's own locale files
  rather than translated here.

Changed

• Modal.okText, Modal.cancelText and the same pair on Popconfirm are now
  nullable, null meaning the word from the locale in scope. Passing a widget
  works exactly as before.
