Delete the code that nothing reaches since tPSGI took over serving

Each of these lost its last caller and stayed behind:

- Trog::Routes::TXT and zone.tx.  TCMS builds its routing table from the
  HTML and JSON routers only, so /text/zone was never served, and the zone
  template had no other reader.
- Trog::Renderer::javascript, which the renderer table never named, and
  with it the JavaScript::Minifier::XS prerequisite that only it used.
- Trog::Auth::primary_user, whose only caller went with bin/build_zone.
- Trog::Themes::themed_template, uncalled since the render refactor.
- Trog::Themes::templates_in_dir and files_in_dir.  themed_templates_in_dir
  replaced them in every caller, because a theme's own forms/ dir hid every
  stock post type from them.  The theme test compared the two helpers, so
  it now asserts what themed_templates_in_dir lists.

Found by ProhibitUnusedDefinitions over bin/ and lib/, and by a search for
modules that no file in bin, lib, t or www names.

+dir of its own would otherwise hide every core post type.
 
 Returns bare filenames, deduped, theme first.  Which of the two files a given
 name resolves to is then up to whoever renders it -- see template_dirs().
