It's only useful for people who used the extension and want to do the
verification. People didn't complain about that and nobody really feels
committed to implement that, so let's remove the temporary code until we
really feel the need for it again.

  - Be short
  - Don't say 'image of', 'logo of', etc.
  - alt="" is fine when the image is purely decorative (duplicating the
    text) or pointless if not seen (QRCode)
  - http://webaim.org/techniques/alttext/ has good tips

This was the user scenario pointed out during the April 3rd meeting to
rescue the old OpenPGP verification instructions. It also makes sense as
the only reason left behind having a direct download.

The old verification instructions will be moved here.

I have no clue if that link is ever displayed in any real-world scenario,
or if some combination of CSS and JS always hides it in practice,
but let's try to play it safe, in case that link is ever used :)

- Put is as a minor in a corner.
- Mark it as clearly unsafe.
- Point to HTTP index to make it less comfortable for non-experts.

And fix an alignment issue on bittorrent-minor.

Now that we have three different actions below the OpenPGP signature,
it's probably worth having a toggle with a bullet list for them.

  - Two of them pointed to the "stay tuned" section. Now that we have
    incremental upgrades, and the subscription form to amnesia-news on the
    homepage of the browser, it's ok not to put that much emphasis on this.

- For some reason this CSS animation didn't work on Tor Browser.
- Let's limit the amount of code that we copy and paste.
- APNG doesn't work on every browser but it does on Firefox which is the
  only supported browser for the extension.
- Animated GIT doesn't handle transparency.

Pause on failure is a rare case (mostly a workaround in Tails if I
understand correctly) so maybe it doesn't deserve a sentence of its own
and people could figure out by themselves that they need to click Play
to start again (and if play doesn't work, then check their connectivity).

It's not working right now.
