[racket] Web-Server: dispatch rules and urls generated with embed/url

embed/url uses the current URL as the base, because a continuation
represents a step in the large computation that that URL represents.
On a technical level, it needs to do this to correctly handle servers
that serve many servlets each with different URLs. It uses the base
url to get to the continuation table, and then looks up the
continuation in the corresponding table.
