Add missing helpers: unescapeHTML and escapeHTML

Browse source 
These helpers are there in the main ConverseJS utils but not in
the headless one; unfortunately they are used in some cases
(while parsing inline emoji) so not having them causes an error.
Ideally we'd patch ConverseJS to include this in the headless
version too, but for now as a quick-fix we're just defining
everything directly in our converse.js itself.
