Add support for HttpProxy

[GoogleCodeExporter]

What steps will reproduce the problem?
1. using the library behind a proxy you'll get an java.net.ConnectException: 
Connection timed out: connect
2.
3.

What is the expected output? What do you see instead?
I expect the library to work behind a proxy

What version of the product are you using? On what operating system?
0.15 (happens on all platforms)

Please provide any additional information below.
com.google.code.geocoder.Geocoder.request(Gson gson, String urlString) doesn't 
include a proxy when opening the stream on the URL. 

It should include a java.net.Proxy.NO_PROXY unless some properties are given in 
order to set up the proxy (maybe another Geocoder constructor receiving a Proxy 
instance).

You can use System-wide properties to mitigate the issue, (-Dhttp.proxyHost 
etc.), but sometimes those cannot be changed

closeable, proxy can be established via

final AdvancedGeoCoder advancedGeoCoder = new AdvancedGeoCoder();
advancedGeoCoder.getHttpClient().getHostConfiguration().setProxy("proxy.example.
com", 8080);
GeocoderRequest geocoderRequest = new 
GeocoderRequestBuilder().setAddress("Paris, 
France").setLanguage("en").getGeocoderRequest();
GeocodeResponse geocoderResponse = geocoder.geocode(geocoderRequest);

nothing like reading documentation, duh..

duh..

Seems like there's an error:

GeocodeResponse geocoderResponse = geocoder.geocode(geocoderRequest);

You're calling geocoder, but I guess you should call advancedGeoCoder instead. 
Or am I missing something?
