New Librebook Integration

[GoldDominik893]

had this really cool idea to integrate Librebook into Liberatube, my idea was that there was a button in the watch page where it could open up a menu for the DMs you have open in Librebook and can share the video you are watching to Librebook. Authentication to Librebook will happen with API keys, the Librebook developer has already added the ability to make API keys associated with the users account, and has also created an endpoint where you can send a message to the general chat. On Liberatube, you can just go to settings and add your instance and API key.

This is the structure that I had in mind:

I think this will be a really cool addition to Liberatube.
