forwarders description wrong

[Firl]

In the "forwarders" property there is an example that doesn't work. The template apparently appends a semicolon.

"10.0.55.15;8.8.8.8" works while "10.0.55.15;8.8.8.8;" does not.

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.
