Add Letterboxd Watchlists

[consier]

It would be great to add Letterboxd Watchlists.
However, naming could become an issue when adding multiple watchlists as they are always named watchlist

The watchlists are a different format from the main lists so will require some more substantional reworking to get functional. I'll have a go later this week.
