Add root redirect for redbean webserver

Browse source 
We have a webserver demo:

    make -j8 o//tool/net/redbean.com
    o/tool/net/redbean.com -v

It's been a little bit confusing that until now you had to visit the
following URL in order to see the default web page:

    http://127.0.0.1:8080/tool/net/redbean.html

The following URLs will now redirect to the above page, but only if
nothing's been defined for those paths and they would otherwise result
in a 404 response:

    http://127.0.0.1:8080/
    http://127.0.0.1:8080/index.html
