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.
