Title: Handle java 'error' event

When running soynode on a system where _java_ was not yet installed, I ran into the following error:

```bash
events.js:72
throw er; // Unhandled 'error' event
^
Error: spawn ENOENT
at errnoException (child_process.js:1000:11)
at Process.ChildProcess._handle.onexit (child_process.js:791:34)
```

This PR adds a handler for the 'error' event, resulting in a readable/catchable error.
