The socket.io server at reveal.jit.su has been updated with socket.io
1.x, which means the examples referring to 0.9.x client libraries
no longer work. Update them with URLs for 1.3.5.
Fixes#1276.
.slides>section and .slides>section>section set the font-weight to
"normal". This overrides any font-weight setting a theme may set at
the body or .reveal level, and requires a theme author to also
specifically set the font-weight for .slides>section and
.slides>section>section. That's tedious and also counterintuitive.
Adopt a saner default by setting the font-weight to inherit.
