git, start experimenting with an alternative/parallel git based sisu document structure

* git, start to experiment with file structure to replace sisupod -g and will
  be in configure options, to track changes to document, enable creation of
  "pods" (zipped content) and allow for remote versioned (or unversioned)
  placement of content source; ideally would end up with two co-existing,
  distinct parse-able structures whether local or remote, the existing directory
  structure with multiple documents and document images etc. and git directories
  with all content associated with a single document (including other language
  versions of it); cannot guarantee at this stage that the file structure will be
  retained, which may mean recreating any directory started and defeat the
  purpose of using it, though it is in a version control repo, so perhaps not ...
  best left alone (unused) for now
