feat: restrict anime trailers, not all animation (v1.0.0.12)

v1.0.0.11 kept every animated trailer away from non-animated content, which
also blocked Western animation (Pixar, Disney...). Only anime should be
restricted.

At download, a trailer is tagged ct4j-anime when TMDB has the "anime" or
"based on manga" keyword, or it is Animation in ja/zh/ko (keywords are now
appended to the details request). At playback, anime trailers are dropped
unless the feature is anime (genre "Anime", or those keywords as tags).
Western animation follows the normal genre/rating filters again.

 changelog:
-  - Animated trailers (anime included) now only play before animated
-    content. Before, an anime trailer could play before a live-action
-    movie or show when they shared a genre like Drama or Action, or when
-    no trailer matched the genre filter. A live-action feature now gets no
-    trailer rather than an animated one
+  - Anime trailers now only play before anime. Western animation (Pixar,
+    Disney, ...) is no longer blocked and follows the normal genre filter
+    again. A trailer counts as anime when TMDB tags it "anime" or "based on
+    manga", or it is animation in Japanese, Chinese or Korean; it is marked
+    with a ct4j-anime tag in its NFO at download time. Your anime is
+    recognised by the "Anime" genre or the same TMDB keywords
