Level: Rewriting History 8 - "A Backwards Level"

Using `git rebase` multiple times, make the commit messages say "This level has to be done in reverse order"

Branches would be as follows, with each word being its own commit, and with the branch in parenthesis:
```
This level (master)
This has to be (hasto)
This done (done)
This in reverse order (reverse)
```

`git gud status` (after interactive rebase)
```
======= Simulating: git log --oneline --reverse
This
level
has
to
be
done
in
reverse
order
