Add screencasts to the main page

It really attracts people.

I've prepared fish completions for salt saltstack/salt#15310 and prepared screencast (gif, using Byzanz). It's a good way to demonstrate features of fish (picture itself says much less).

I think it could look like this: http://dimsemenov.com/plugins/royal-slider with 3-4 short screencast showing autocompletion, multiline editing, fish web configuration.

I think screencasts would be good. Perhaps we could self-host http://asciinema.org screencasts? It uses HTML5/js. It's rather nice not having any large images/movies for people to download, and having them render with real fonts at whatever size their browser wants at native resolution.

Yes! If anyone wants to put these together I'll be glad to upload them.
