Title: Geo distance range filter implementation

Here is implementation of geo_distance_range filter
http://www.elasticsearch.org/guide/reference/query-dsl/geo-distance-range-filter.html

I've also refactored `Elastica_Filter_GeoDistance` and moved common logic with `Elastica_Filter_GeoDistanceRange` to abstract class `Elastica_Filter_Abstract_GeoDistance`

Tests are included to.

Fixed #258
