Tweak CSS so really long breadcrumbs wrap nicer

Use display inline instead of floats so that manual sections with really
long titles wrap nicely instead of acting as a block.

Move the padding and font mixin onto the containing `ol` instead of the
`li`s so that the spacing underneath the breadcrumbs stays good.

Handle footnotes in manual sections

Manual sections containing footnotes now have an h2 added for the
footnotes detail at the bottom of the body.

Style it appropriately.

When a user clicks on a footnote link, open the footnotes section so
that the footnote content is visible.
