enhance for geoxml3: add proxy

[GoogleCodeExporter]

From:  Thanh Trung Nguyen via email

Here I write you this email to send an enhanced version of GeoXML3.

In this version, allow you to fetch KML file from an external source, a work 
around for the "Same origin policy".

Schema: GeoXML3 <=> proxy <=> KML file

This way, you fetch the KML file using a proxy like php script instead of 
fetching it directly using Ajax.

It's very easy to implement, simply add a correct path to the proxy {"proxy": 
"proxy.php"} to your JSON option.

The example proxy in this issue is fully open, and there are people who will 
tell you (if you have a rather targeted use like always getting from google or 
similar single source) you might want to make it more secure.  See this wiki 
from the geoxml project for additional information:
