Use text not images for screenshots

[samuelcolvin]

pgcli is awesome. Thank you.

Would be very useful (and better for SEO) if the screens on / and /features where text (with html to style them) not images.

This would allow searching and copy & paste.

I realise that some of the screenshots include the drop-down context manager which might not be possible to capture in html, but the rest shouldn't be too hard.

See https://python-devtools.helpmanual.io/ for an example of what's possible without too much trouble.

Hmm we could also use https://asciinema.org/ ?

Perhaps the screenshots have changed since this issue has been opened (7 years ago!), but I find the screenshot on the home page good enough. I don't think we would gain anything in SEO since it merely shows SQL. And styling the auto-complete dropdown in HTML is probably not worth the hassle. The same goes for the auto-completion page and the syntax colors page. As far as I can see, these are the only pages that have images (screenshots).

What would be nice, though, is more complete alt(ernate) text for images for accessibility. I propose a fix for this in #65.

Screencasts such as Asciinema could be nice. There is a distinct issue #8 for a follow-up.
