Make action caching aware of different formats for the same action so that, e.g. foo.xml is cached separately from foo.html. Implicitly set content type when reading in cached content with mime revealing extensions so the entire onous isn't on the webserver. PDI MORE CACHING TESTS [Marcel Molina Jr.]
