Move away from Trakt

[d3mystified]

Now that Trakt people have lost their minds and limit accounts to just 2 lists, I think it's worth integrating with alternatives:

• mdblist
• simkl

Should be pretty straightforward with https://mdblist.docs.apiary.io/#reference/0/modify-static-list/modify-list (just pass the tmdb or imdb id to mdblist).

This is definitely planned. Will be done as soon as life allows. We'll be using TMDB though. As far as I'm aware MDB is a paid service, no?

Edit: it looks like there's a free tier as well but it would probably be worthwhile to make this a user choice.
