As noted in the previous release notes we are going to add a "directory:walk" function:

  • Given a starting point
    • Walk it, recursively, and invoke a callback with the complete path-name.

Annoyingly this can't go in the builtin-package, as it needs to invoke the callback..

Implemented directory:walk

Sample usage looks like this:

```
(directory:walk "/etc" (lambda (x)
                         (if (directory? x)
                             (print "Got directory: %s" x)
                           (print "Got file: %s" x)
                           )))
```

To avoid the complexity of adding this as a built-in form the
implementation creates "directory:entries" to return the contents
of the given path, recursively.

If we have a list of file/directories, and a function, we can just
use apply to do the magic.

This closes #34.
