Static file caching for the Website service (#6)

Browse Source 
This PR contains the work done to add cache-control headers to static file responses by configuring the `FileMiddleware` middleware to tag served static files with *Cache-Control* directives, tuned per media type.

To provide further details about the work done:

* Added a cache control that sets per-type policies: text assets (CSS/JS) get public, max-age, must-revalidate; images get public, max-age; everything else gets a default public, max-age.
* Files stay validated via `ETag/Last-Modified` header.
* Made the max-age values configurable, with defaults, via new cache constants.
