SSH Keys Without Passphrase's

[jpe42]

Is it possible to support private keys without passphrase's? I get the following error with my current key.

/usr/local/lib/node_modules/remtail/node_modules/ssh2/lib/client.js:156
        throw new Error('Encrypted private key detected, but no passphrase giv
              ^

I have added support for ssh keys with passphrases in v0.0.4. It should autodetect them and prompt for the passphrase.
