Title: Use Rack::Lint in all tests

This contains the rest of the changes proposed in #290.

I fixed Rack::ETag to set an empty String instead of an empty Array as the value for Cache-Control. In #290 I already changed Rack::Cascade::NotFound to include a Content-Type header.

I ran the tests on 1.8.6, 1.8.7, 1.9.2 and 1.9.3, and fixed all warnings.

Do we also support Rubinius and 1.9.1? Then I'll check them too.
