Move styles off of compiled HTML and into the prendus-view-question component

[lastmjs]

I think it makes sense to keep the compiled HTML as simple as possible, and that means having minimal to no styling. I think the styling should be left up to the consumer of the compiled HTML, the interpreter. The Prendus question components are a consumer. I ran into a problem while taking off the styling, and I believe it is because of the Shadow DOM polyfill in Firefox. Until Firefox and Edge ship native implementations of Shadow DOM for at least 2 or 3 browser versions, I wouldn't try to put the styles on in the consumer component. But once we can, we should move the styles.

Might not be a good idea, we probably want the AST to have some style information in it, for example to size images and essays and code editors
