Improve titel of season and episode listings

[RobertMe]

The current title for the season listing is Seasons, I suggest changing this to the show name. The title for the episode listing is Episodes, suggested title is <show name> S<season number>.

Same can probably also be done for other listings. But these are the ones I use (and see) most of the times :smile: So it's probably best to check all of them.

Yep, valid for all of them.

During implementation I saw these names are also used as subtitle. So if we want to change the title of the models we'd probably also need to revise the subtitles. And we'd need to take the "Recent" listings into account. As in those cases you don't have a tvshow + season, for example, to use as title
