[Fix] addition of prefixing eval to find command required certain values to be escaped differently for proper function
      of '-r|--recent'
[Fix] util-linux 2.23 supports 'column' command with '-o' but earlier versions do not, resulting in scan reports
      generating empty hit lists
[Fix] importconf was setting invalid vars for custom signature imports; correct variables are import_custsigs_md5_url
      and import_custsigs_hex_url
[Fix] multiplying maldet monitor processes due to 'ps' command expansion under parent bash process on CentOS6
[Fix] added default installation path to ignore_inotify to prevent monitor looping when '/' is scoped into

         $hostid.$RANDOM.$filename.[ascii|bin]

         source form from:
         https://github.com/rvoicilas/inotify-tools/wiki/
         binary versions are also available from dag repo at:

[Change] use of clamav engine output statement now more verbose
[Change] previously LMD only linked clamav signatures into clamav data paths on install, this is now done after each signature update
[Change] maldet.sh init script exites code 1 on status check when maldet monitor mode is not found running
[Change] monitor mode now invokes every 15 seconds, legacy installations will preserve 30 second cycle timing

      as a result of lstat errors on the custom user signature files stored under $tmpdir
[Fix] clamd.conf configurations containing FollowDirectorySymlinks/FollowFileSymlinks set to false results in the
