There's no list I don't think..

From what I can remember the main things were -

Glue - Sticking things without movement
Nail? Idk - Allows objects to pivot
Motors? makes things move..
Cut tool - Lets you reshape & cut things
Different materials
Stickers
Brains! Turns inanimate objects into enemys.
Switches - "Adds logic into the game" to quote someone. Lol.

What I'm really hoping is that they give different objects different weights ;/
