El prettier formatting for some

This is a mostly unnecessary commit that there are probably better tools/ways to do it.

But I enjoy the challenge, and I don't know of a better tool yet.

This converts the handful of classes that pretty_inspect leaves in-line to an easier to read format.

```
#<User @attributes={id: 1, name: "User Name}>
```

Becomes:
```
#<User
  @attributes =
    {
      id: 1,
      name: "User Name
    }
>
```

It causes a handful of things that are easier to read as they already are to be harder to read, but overall, the benefits outweigh the issues.
