contrib/gis/maps/google/gmap : script() string formating

[martync]

The property named "script" in contrib.gis.maps.google.gmap.GoogleMap has a wrong string formating.
​https://github.com/django/django/blob/1.5c2/django/contrib/gis/maps/google/gmap.py#L134-L137

        return format_html('%s\n  <script type="text/javascript">\n//<![CDATA[\n%s//]]>\n  </script>', self.api_script, mark_safe(self.js))

while it should be :

        return format_html('{0}\n  <script type="text/javascript">\n//<![CDATA[\n{1}//]]>\n  </script>', self.api_script, mark_safe(self.js))

I have created a pull request for this bug : ​https://github.com/django/django/pull/1379
I will write a testcase.
