    Allow env registry paths to be relative to env file

    The default base_url is now derived from the location
    of the environment file, so now resource registry paths
    can be relative instead of absolute URLs.

    This change also includes the following:
    * more complete test coverage
    * refactor of _process_environment_and_files and
      _get_file_contents to make test coverage easier
    * use the full URL instead of just the file name in the
      'files' field to avoid key clashes
    * make _get_file_contents less specific to the resource registry
      so it can be used for other inclusion tasks
    * stop calling _get_file_contents recursively so that deep URLs
      do not get loaded, instead call _get_file_contents on
      resource_registry and resource_registry.resources.*
