#53 Add google maps link for geo tagged images

[Xander Hendriks]

I recently started to use a freeware program to add GPS coordinates to my photos. As I've been using phpGraphy for many years I didn't want to look for another tool that has similar functionality and adds the google links for geotagged images. Instead I modified 2 phpgraphy files to get the wanted information displayed next to the images.

I attached the modified files. The lang_en.inc.php file makes sure that a link is displayed underneath the image. And functions_metadata.inc.php was modified to do the actual parsing of the Exif GPS coordinates.
