Upgrades dependency versions

This pull request updates the dependencies to their current version and thereby fixes an issue with Node 0.10.x:

```
(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.
(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.
...
```

resulting in an `RangeError: Maximum call stack size exceeded`.

With these new dependency versions, my node application with passbook creation works 100% fine again.
