Cache on server feature

Server will download video from supported players and add as raw video to playlist (only youtube is supported for now).

Cache for YT player is available after installing optional dependencies, see readme. For cache size see `cacheStorageLimitGiB ` in config.

There is also minor ux improvement, latest checkbox states will be keeped in local storage now.
