Trending, most watched and anticipated movies and series from Trakt

With an empty search box, Movies and Series show one of Trakt's public
lists: trending now, most watched this week, anticipated, popular, and
for movies the US box office. [ ] switch lists, r reloads. Each entry is
looked up in Radarr (tmdb:) or Sonarr (tvdb:), so it behaves like a
search result: details, poster, tick when in the library, add, releases.

Needs a Trakt client ID: new optional trakt.client_id setting (Config
view section "Trakt", ARR_TUI_TRAKT_CLIENT_ID), masked like the API keys
and checked by Test. ARR_TUI_TRAKT_URL points at another server for
development.
