The geoGetCoors method does not use the Google API-key in requests

[fl0pp]

It seems like this project is dead, but I use it in an old project that is still running.
I found a bug in the API-call to Google in the geoGetCoords method. It does not use the API-key provided by Google in it's API-calls.

I edited line 2648 to the following:

$_url = sprintf('https://%s/maps/api/geocode/json?sensor=%s&address=%s&key=%s', $this->lookup_server['GOOGLE'], $this->mobile==true?"true":"false", rawurlencode($address), $this->api_key);
