[Feature] Implement get('markers')

[DevDaveo]

Besides providing getting objects by an index it would be great to allow getting an array of all added markers (or infowindows, polygon etc) as Array of these objects.

I've discovered you can get the array of markers this way:
$('.map').gmap3().get(1)

If using the fit() method, the array is at:
$('.map').gmap3().get(2)

You can also save a reference to the map when you create it and that to access the markers
