Subject: [PATCH] added key disableHostKeyChecking that if set to true will
 cause smartcopy to bypass the built-in SSH host key checks. This is useful if
 you dont want to worry about the known host file across reboots. If this key
 doesnt exist or is false, it is the admins responsibility to ensure the known
 hosts file is up to date
