Shuffle words have crappy documentation and no examples
They have this:

```
Shuffle word. Rearranges the top of the datastack as indicated in the stack effect pattern.
```

Not very helpful to new-comers who don't know what datastack means, or what exactly a stack effect pattern is.

At the very least it could link to help articles, better would be to have "shuffle-specific" documentation for the common words.
