Alias for clean_text function: escape?

[ashrub-holvi]

Sorry if I misunderstand something, but for me looks like clean_text function doesn't clean html or text, but do escape for html.
I understand that it's just mirroring API of ammonia, but perhaps good to have some, better named alias.

Also, Python already has html.escape(). It would be good to note how nh3/ammonia differs.
