This adds in the option to have "deny known clients" in dhcpd.conf
This is applied to the range command so applies to the dynamic addresses
given.
If you have just a range statement say in blue then if you are not using
vlans you could have the situation where a known host in green might end
up getting a lease from the blue range. Here a deny known-clients makes
sense. Your range in this case would be limited to only unknown clients if
deny known-clients was selected.
dhcp WUI has been modified to add in this command. Error message has been
added to check that a range has been specified if the deny unknown clients
checkbox has been selected.
Language files updated with additional items (English, German & Dutch).
