Feature: Show img alt text (#168)
Let's start small by showing the ALT text of IMG. This is rudimentary,
but avoids those otherwise completely blank chapters.
I feel we will need this even when we can render images if that
rendering takes >1s - I would then prefer rendering optional and showing
the ALT text first.
