Recent Node seems depeciates sys.print

[wsuff]

This creates a warning on each output print in chromix-server.

I made a local change that seems to resolve this so I figured I'd mention it. Might not be the best fix so I will defer to the project as to how it's addressed in the next npm package.

  print = require('console').log;

  echo = function(msg) {
    return print("" + msg);
  };

It appears log already has an endline. Using node v0.12.1
