Add cache-busting and server headers with a wrapper.

Browse Source 
In order to support custom headers for various response types,
  this commit adds a wrapper type, ResponseWrapper, which can service
  all types of response in `bin`.

For paste objects, the preferred `Last-Modified` is used, so that caches
  can compare their exact timings with the HEAD response when
  revalidating.

For static objects, an `ETag` is used instead, based on the Cargo version
  and git hash of the codebase at compilation time; a `build.rs` is used
  for this.
