Toggle to see raw LaTeX

[davidfarmer]

Let an instructor easily view the raw source of the answer.
A use case:

I'm teaching my students LaTeX. I'd love to see the crazy stuff they are doing and point then in the right direction. Latest: \langle instead of < ! Stamp out bad LaTeX, one mathematician at a time.

I guess I can view it in the Inspector, but a toggle might be really useful. Not high priority, of course.
