New csf v6.20

Changes:

• Introduced a new directory structure to get closer to the Linux
  Filesystem Hierarchy Standard (FHS):

  /etc/csf/           - (mostly) configuration files
  /var/lib/csf/       - temporary data files
  /usr/local/csf/bin/ - scripts
  /usr/local/csf/lib/ - perl modules and static data
  /usr/local/csf/tpl/ - email alert templates

  Existing data and templates files are migrated into the new structure automatically. Some files and directories are symlinked to /etc/csf/ for backwards compatibility and ease of use. See the following for individual file locations in the new configuration:
