added: config: base_url_redirect

when true the server checks whether HTTP_HOST environment variable
       is the same as base_url from the config (of course without the 'http://' part
       and the last slash) - if it's not the same then the server
       redirects you into a new location base_url+REQUEST_URI
changed: variables env_* from Request are never null (after Request::Read())
       if the server didn't set such a variable it will be pointing into an empty string "\0"
