Some error reporting would be great

Thanks for the awesome plugin!

Is there a Github location through which I could possibly contribute?

I’m not clear on what exactly my Google API ID is, and the plugin shortcode seems to die quietly rather than returning a useful error message.

I have added the following lines to modules/reviews.php at about line 58.

// Output some useful error message if result fails
if (array_key_exists('error_message', $data)) {
	return 'Google API returned an error message: <br>' . "\n Error Message: " . $data['error_message'] . '<br>Try this URL in a browser and see what result you get: <a href="' . $curl_url . '">' . $curl_url . '</a>';
}
