Add a hook that Map widget subclasses can use to provide more data to the #64

Add a hook that Map widget subclasses can use to provide more data to the javascript... useful for eg. adding custom base layers

For example, I have mine return this dict; notice the value is a JSON string: {'extra_base_layers': '[{"url": "http://maps.opengeo.org/geowebcache/service/wms", "options": {"wrapDateLine": true}, "params": {"layers": "openstreetmap", "bgcolor": "#A1BDC4", "format": "image/png"}, "class": "WMS", "name": "OpenStreetMap (OpenGeo)"}]'}

And then my template looks like this: https://gist.github.com/1002867

This is a more general-purpose feature that could make #60 and #47 unnecessary.
