Completed update of unit tests for core i18n API (language in lang attribute)
Completed update of unit tests for core i18n API (language in lang attribute)

The config was still used in unit tests for get(), getString() and
filtetHtml(); I replaced its use with setting of the 'lang' attribute of
the root HTML element, mostly through the sandbox method selectLanguage().

Direct use of the 'lang' attribute remains in reset code:
document.documentElement.removeAttribute('')

Should this be part of the behavior of reset() in lb.base.i18n?
