Recent changes to jQuery Terminal (probably escape of XML formatting) broken automated Jargon example.

This is not an upstream issue, animation of XML formatting works fine:

The problem is a combination of async figlet.preloadFonts and implicit exit.

This is the proper figlet code:

## import JavaScript objects into Gaiman
import figlet from "https://cdn.jsdelivr.net/npm/figlet/lib/figlet.js"
import Array
import Promise

figlet.defaults({
    "fontPath" => "https://unpkg.com/figlet/fonts/"
})

new Promise(lambda(resolve)
  figlet.preloadFonts(Array.from(["Standard"]), resolve)
end)

Created a PR in figlet.js project to make the API promise based:

• https://github.com/patorjk/figlet.js/pull/129

Turns out that figlet.text() is already promise based, so you can use it without preloading the fonts.
