Clarification on the snarkOS --ip option

[kellpossible]

Connecting using an ip address seems to require the port to also be specified. Failing to specify the port results the in the following error message:

Error: Crate("std::net::AddrParseError", "AddrParseError(())")

[kellpossible]

perhaps the command line argument should be renamed to address to imply that it involves both the ip and the port.
