Remove All of Base Url From Registered Partial Name

Instead of this:

somefile.hbs

```hbs
{{> blocks/header}}
```

gulpfile.js

```javascript
var options = {
  batch: ['./src/hbs/blocks']
};
```

Now that the base url is removed, we can do this:

```javascript
var options = {
  batch: ['./src/hbs']
};
```

This is more flexible and allows partials to be organized in any way
without having to update the gulpfile.
