Nameserver argument isn't working with a list on DNS

[LucasJanin]

It looks like the nameserver argument isn't working with a list of DNS
NAMEinator is only using the first on the list:

./NAMEinator -nameserver 208.67.222.222 208.67.220.220

starting NAMEinator - version custom
understood the following configuration: {numberOfDomains:100 debug:false contest:true nameserver:208.67.222.222}
