Disable textbox autoscrolling while on screensaver.
[videodb] Don't remove TV shows with no episodes.

That's not configurable and this shouldn't be the default behavior.
[settings] Promote hideemptyseries to GUI setting.

This promotes videolibrary.hideemptyseries from an advanced setting to a GUI
one.  This is enabled by default.
[jsonrpc] GetTVShows: always return empty tv shows regardless of user setting
jsonrpc: bump to 6.21.3 after eb94146883d5b9f521e16966986a66e9cfe93df8.

6.21.3 may be unreliable.
