Manual of Style: Change style sheet to 2016 version

Dear spec-prod,

Could we change the stylesheet for the Manual of Style and related documents to the 2016 spec stylesheet? This would make them easier to read. They do need some additional bits for stuff like “Publication Policies”, but that shouldn’t be too hard to work in.

I looked on GitHub, but it seems the manual pages aren’t on there. Would it be possible to place them on there so it’s easier to make changes like this (in the form of PRs)?

Cheers.
