Sending PASS to password protected irc server prepends :

[petecheslock]

Seeing an issue using node-irc with a password protected IRC server.

When sending the PASS in this section:
https://github.com/martynsmith/node-irc/blob/master/lib/irc.js#L510

It prepends : to the password (and thus the password fails)

It looks like from this line:
https://github.com/martynsmith/node-irc/blob/master/lib/irc.js#L603

Here is what we saw when we enabled extra logging on our IRC server:
INFO | server.commands | #<NioAcceptedSocketChannel [id: 0x00b15b0c, /10.9.1.11:45366 => /10.194.154.5:6667]> sent PASS-> :blah
INFO | server.commands | #<NioAcceptedSocketChannel [id: 0x01b3358f, /10.9.1.11:45467 => /10.194.154.5:6667]> sent PASS-> :blah
INFO | server.commands | #<NioAcceptedSocketChannel [id: 0x00165861, /10.1.1.17:37850 => /10.194.154.5:6667]> sent PASS-> blah

The first 2 lines were using node-irc - the last one used a generic IRC client.

Any ideas?
