Merge pull request #28 in IAAS/cis-hardening from dev/cherlin/cis-root-dir-in-env to master

* commit '5b11b1628a690e0bbd9d34cd5b83dbe74ac6fba7':
  Expand tabs to 4 spaces and trim trailing spaces
  Remove unnecessary CIS_ROOT_DIR empty assignation
  Applying batch edit to all hardening/*.sh scripts for new CIS_ROOT_DIR management
  Changing CIS_ROOT_DIR management in env in bin/hardening.sh
  Change src/skel to allow setting CIS_ROOT_DIR in env and not just sourcing /etc/default/cis-hardening. Making the whole lib more versatile.
