Shorthand for registering partials at initialization didn't work for me.

With settings like this

```javascript
$.handlebars({
    templatePath: 'js/templates',
    templateExtension: 'hbs',
    partialPath: 'js/templates/partials',
    partialExtension: 'partial',
    partials: ['element'] // need to register partials
});
```

`resolvePartialPath` would always return empty string, since `settings.partialPath` was not set. Moving settings before registering partials (as you can see in my commit) worked for me. I tried also with separate registering and it worked. Hope I didn't break something else.
