[plt-scheme] Using web-server/servlet-env to host a root level servlet

There is not an easy way to do this. Here's a hacky way:

1) Remove the filter:make around (let-values in servlet-env
2) Change (build-path servlets-root servlet-path) to (build-path servlets-root)
3) Pass "" as #:servlet-path

Another way is to make a custom dispatcher that rewrites the URLs that
come in to contain the ".ss" file. For example:

(define (rewrite regex inner-dispatcher)
 (lambda (conn req)
  (inner-dispatcher conn (make-request ... (string->url
(regexp-replace (url->string (request-url req)) regex)) ...))))

and make that the top-level dispatcher (perhaps using
web-server/run.ss as a base)
