Options not propagated to mapbox

[dan-castle-rock]

It appears additional query parameters are not being propagated to mapbox. For instance, the addition of proximity is not added when set as an option.

     var proximity = longitude.toString() + ',' + latitude.toString() ;
     var geocoder = L.Control.Geocoder.mapbox( access_token, { geocodingQueryParams : { proximity: proximity } } ) ;

I did a local fix to my installation by doing the following:

        var params = L.extend( { access_token: this._accessToken }, this.options.geocodingQueryParams );

        Util.getJSON(this.options.serviceUrl + encodeURIComponent(query) + '.json', params, function(data) {

for the mapbox geocode function (approximate line 416)

This has been fixed via #164.
