Further MAC issues: in target area, the manual ip field was target
ip/mac address - changed to IP-Address
Also implemented a plausicheck, if an addressgroup with mac addresses is
used in target area, theres a hint saying that the rule will not be
applied for mac hosts
The converter scripts procude a lot of error, when they get executed on a system with
a previously installed version of the New Firewall or they get run twice.
In this case the scripts will detect that their input files are missing and will exit with
an error message. The scripts now also check if the input files are empty (no corresponding
rules created) and will exit with an nothing to do message.
Now all "active" Strings from all languagefiles are checked against the old rule to find out if logging is enabled
