Removed ip_ver parameter

I removed this because I realized I could just check the IP version inside
the constructor. The Sock constructor now checks the address passed to it.
Like before, if the address is neither v4 nor v6, an exception is thrown.
Since the Server and Client constructors call the Sock constructor, no change
was required in these files, except passing the right number of parameters.
