Fixes full property not passed for direct gets

In the example below, an array containing the Google marker objects is returned when it should return the "embedded" objects (containing id, tag, data, etc) instead.
```
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!
