Title: Add callback support to walk.

```javascript
var shifter = require('shifter');

shifter.init({ cwd: '/some/valid/path' }, function() {
console.log('== shifter finished ==');
});
```
__== shifter finished ==__ logged after shifter completes.

```javascript
var shifter = require('shifter');

shifter.init({ cwd: '/some/valid/path', walk: true }, function() {
console.log('== shifter finished ==');
});
```
Callback never executed.
