- added --version option.
- added support for printing help if no options given, or if
'help' was used (i.e. 'openstack-auto-commands help')
openstack-manuals was also added to .gitignore so that
running the 'doc-tools-update-cli-reference' script will
not affect the os_doc_tools repo if the tool is run
within the repo.
