Fixes full property not passed for direct gets

In the example below, an array containing the Google marker objects is returned when the "embedded" objects (containing id, tag, data, etc) should be returned.

```
var markers = $("#test").gmap3({
  get: {
    name: "marker",
    full: true,
    all: true
  }
});
```

This suggested change fixes this bug by passing the fourth parameter to the ``get`` function.

Thanks!
