return locale based on HTTP request header ACCEPT_LANGUAGES.
We need languages to get locale, and the locale on the request
object gets this wrong (removes territory part of locale). This
does essentially what ZPublisher.HTTPRequest does to load a
locale, but with a fixed (predictable, correct) adapter.
zope.publisher.browser.BrowserLangauges is an adapter with
fixed behavior to correctly get languages. Other adapters in
Plone packages (e.g. PTSLanguages) may interfere with
ZPublisher.HTTPRequest.locales loading territory, so we prefer
a fixed adapter rather than an adapter looked-up by registration
via IUserPreferredLanguages.
