  Use `<sup>` for exponentiation

This renders much better in HTML and the text format does not suffer for
it.

Conversion process was mechanical:

```
sed -i -e 's/\^\([0-9][0-9]*\(\|\.[0-9][0-9]*\)\)/<sup>\1<\/sup>/g' draft-*.md
sed -i -e 's/<\/sup> - /<\/sup>-/' draft-*.md
```

Cleanup used emacs because I know that wraps reliably.

```
emacs $(git status --porcelain | cut -d ' ' -f 3 -)
```

With the macro sequence:

```
C-X ( C-s '<sup ENTER M-q C-x )
```
Then for each file it was basically just:

```
C-u 99 C-x e C-x C-s
```

Though I had to revert changes to the changelog.
