Prettier nodes

I've had the idea to use a "plugs and sockets" metaphor for connections between nodes. So each type of output has its own plug shape that you can grab and plug into a corresponding input socket.

Maybe grayscale outputs are Shaped like a >:

• The right side of a Separate node has 4 |> plugs sticking out.
• The left side of a Combine node has 4 > sockets in it, with an accentuation for the > shape where the |> plugs fit.

This makes it really clear what socket does what without having to only rely on colors, like many other programs do.

Sockets could also be shaped like a D, or like a square, etc.

Colors could go along with each socket for even better differentiation.
