Description:
------------
Locale::acceptFromHttp could only returns with a string. But HTTP Accept-Language could offer more than one language tag with priority. Why not to return an number-ordered-array like:

array
(
  0 => language tag 1,
  1 => language tag 2,
  ...
)

Ordered with priority offered by HTTP?

At least this yes. But in each application we will have a code that looks similar to this:

$supportedLanguages = ['de_DE','en_US'];

foreach (Loacle::acceptFromHttp as $locale) {
  if (in_array($locale, $supportedLocales)) {
    return $locale;
  }
}
return $defaultLocale;

Why a acceptFromHttp if it is useless? The best matching is not useful at all. A list of matching locales is at least useful. But even better will be a function that gives the locale we want to use:
public static function acceptFromHttp($header, $supportedLocales, $defaultLocale)
