Title: broken symlinks = bad time for du

Produces an error like so:

```
Error: ENOENT, no such file or directory '/path/to/symlink'
```

This now adds size of symlink to total.

Another option would be to should ignore symlinks or perhaps even try reading the target, and fail silently if it can't.
