More variety for jigsaw edges#1535

The edges of the jigsaws of different sizes seem to be predefined. While from my experience this is fine as I won’t remember the form of the pieces till the next game, it would still be nice to have some more variety here.

Pieces could for example have:

• Other pin forms on the pieces (pins being the parts of a piece holding it to another piece in real world jigsaws.)
• Pins that are not all the same, so not every pin fits in every hole
• Round or non 90° edges so the jigsaw is not just made of rectangular pieces
• No pins at all (as they are less necessary for a digital jigsaw)

It has unique pins per piece/side. And I’m working on adding hexagon pieces to it.
