Feature request: more automatic sync options

[denny-cube]

It would be great to have more option for automatic sync, for example:

• Media Server Connections (Jellyfin/Emby/Plex): add "AUTO PUSH" sync on top of the current "AUTO PULL" sync (not present for Jellyfin, not sure for the others since I don't use them).
• Trakt: add both "push" and "pull" automatic sync.
• Simkl: never used it, but seems very similar to Trakt, so why not doing the same?

And thanks as usual for your wanderful work on this project!
