Improve navbar UX logic for #233

This change takes us away from using overflow:hidden on body by
default, only toggling this using a new `open` class when the navbar
has been expanded. `open` is toggled on body in the same places as it
is for the appear and navdrawer.

In the 1200px media query, negate the `.app-bar.open, .app-bar.open ~
main transform` to remove the white area (~250px out) displayed. This
generally seems to be a FF only issue.
