[web] set Vary response header to "Accept-Language" when using content negotiation
This is slightly annoying because the response actually only varies
based on the language we decide to send, which has much fewer possible
values than Accept-Language, but that's not in the request, so we can't
easily use it. Deployments using varnish or similar and controlling the
set of available languages will likely want to override this to allow
reasonable amounts of caching.

Documentation
~~~~~~~~~~~~~
Please keep rules semantically linked grouped together, with a comment about
what they are for.
Recommendation
~~~~~~~~~~~~~~
- Try to use existing classes rather than introduce new ones
- Keep things as simple as possible while in the framework
- Think about later customization by application
- Avoid introducing a new CSS file for a few lines of CSS, at least while the
framework doesn't include packing functionalities
