Title: Notebook stylesheet width 1170px->98%

Starting somewhere around 1.x, notebooks became restricted to a max width of 1170px, which is really annoying when you're working on most monitors. Replacing all instances of 1170px with 98% gives a much more reasonable appearance and seems to scale fine even when the display is smaller.
