Bahuvrihi Tap (Task Application)

Certain parts of env configuration is currently tied to symbols or strings. (strings for tap.yml files, for example).

This should have indifferent access, in from_gemspec

        config = {
          'root' => path,
          'gems' => dependencies,
          'load_paths' => spec.require_paths,
          'set_load_paths' => false
        }
