v3dv: --redirect (--redirect=dir_path) & --dump (--dump=dir_path) + consequences

* --dump places output in directory specified, if none specified in the current
  directory (pwd).
* --redirect places output in subdirectory under specified directory,
  subdirectory uses the filename (without the suffix). If no output directory is
  specified places the subdirectory under the current directory (pwd).
* html, css incorporated into each file (concordance & manifest included)
* html, xhtml & xmls, css copied into css subdirectory (not used by html as
  embedded)
* html xmls, images copied to output directory
* no links to manifest
* manifest with relative links only
* longer html filenames given to avoid names clashing (e.g. for toc, manifest,
  concordance)
* html, epub, remove manifest toc links
* -j copy images associated with file (images used by html & xmls)
  * automatically invoked by --dump & redirect
* v3 v3dv: document --redirect, --dump, -j update sisu_commands.sst
