Rack-based asset packaging system

Sprockets::Server#call

`call` implements the Rack 1.x specification which accepts an
`env` Hash and returns a three item tuple with the status code,
headers, and body.

Mapping your environment at a url prefix will serve all assets
in the path.

    map "/assets" do
      run Sprockets::Environment.new
    end

A request for `"/assets/foo/bar.js"` will search your
environment for `"foo/bar.js"`.
