Conversion [Alpha 31]

This update adds the Player Converter piece.

I have considered a dungeon for this for a long time, but never reviewed the basic premise: What happens when the player is a converter?

After the initial rush of power you realise you can't open doors or gain food from making allies. You have to get creative.

In addition to 10 new puzzles about this piece, the Endless dungeon has been updated: You now start as a random player piece: walker, turner, or converter. The progression of Endless has also been revised. It goes through the entire catalogue of pieces as normal, then chooses pieces at random. Endless is a place of strangeness and ill-fitting rules, it should lean into that.

A mac update should arrive soon, it just depends if MacOS agrees.
