Change default layout: below → beside

Change default layout: below → beside

:(

Below layout is nicer, but has two problems:

1. The page break logic seems to be broken.  Some pages have content run
   off the bottom.  Other pages get a single line.  This seems to be a
   bug in the wrapstuff package.

2. There's a problem I don't understand where LaTeX complains about the
   \wrapstuffclear following a \footnote, saying:

      ! LaTeX kernel Error: Not in vertical mode.

      Starting a paragraph with \RawIndent or \RawNoindent
      (or \para_raw_indent: or \para_raw_noindent:) is only allowed
      if LaTeX is in vertical mode.
