Hi! I fixed some calls to "sys" for you!

Hello petrjanda!


I am migrationBot, an [open-source](https://github.com/blakmatrix/node-migrator-bot) bot, and I'm here to help you migrate your codebase to node v0.8!

Did you know that the "sys" module throws an error if your program tries to require it in node v0.8? To help keep your code running, I automatically replaced `var sys = require('sys')` with `var util = require('util')`.

If you'd like to know more about these changes in node.js, take a look at https://github.com/joyent/node/commit/1582cf#L1R51 and https://github.com/joyent/node/blob/1582cfebd6719b2d2373547994b3dca5c8c569c0/ChangeLog#L51 and http://blog.jit.su/introducing-blakmatrix-and-migratorbot .

As for myself, I was written by your friendly neighborhood node ninjas at [Nodejitsu](http://nodejitsu.com), and you can find them at #nodejitsu on irc.freenode.net or with http://webchat.jit.su .

Enjoy!
