bundle modern version of node for cedar-14

There's an error when using node 0.4.7 on cedar-14. This is due to libssl 0.9.8 being on that stack image:

```
ExecJS::RuntimeError: node: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory
```

Unfortunately, you can't easily statically compile node 0.4.7 against libssl 0.9.8 or compile against 1.0.1.

This forces users onto a newer modern node but they have to opt into this.
