commit 34fa53060d93a4709ba8dfd63194cd798427260e
Author: Matthew Finkel <Matthew.Finkel at gmail.com>

Select language and language direction based on order in header
We guess which language gettext will choose by iterating over
the languages in the Language header and selecting the first
one we support. We assume a user will prioritize languages in
their browser. We then render the page using the selected
language, or English if it is no available. Bug fix on #9157.
(cherry picked from commit a31c592eadd72a659f22497f66e77fb90c6c207b)
