#990 Use client broadcast address on WoL

Some universities have computers in a different subnet where the
ogServer is, but ogServer WoL functionality only supported to send
packet to its own subnets. This commit solves this.

Now ogServer sends two WoL packets per client, one with the broadcast
address of the interface indicated in the config file, the other with
the broadcast address calculated with the address and netmask of the
client.

To ensure that the second WoL works correctly you must configure
correctly the IP and netmask of the clients. Also, you have to configure
the network of your organization to route WoL packet to the correct
subnet.
