add option for snapshot-id suffix to __version__

1.  The added suffix is in the form YYYYMMDD and that is all.

2.  Code is added to classes my_sdist and my_rpm to check if
a snapshot id is requested (--snapshot or -s) and, if
requested, to append the id to the value of cliconfig.__version__

3.  The added suffix only applies to the name of the sdist-tarball
and the rpm spec file it includes ... the "internal" version
remains unchanged.
