Up to now the root of the webserver filesystem was always the current directory. Now an optional file 'wwwroot.cfg' is read. If present its content is used as prefix in the conversion of http paths to local paths. This prefix may be a relative path as well as an absolute path.

This is especially useful for the cc65-based targets as it ain't possible there to "just change into the wwwroot directory and start the webserver using its pathname".
