Shortcode function breaks ob stack

There is a wrong use of ob_clean() function in line 423 of the wp-google-map-plugin.php file. Instead of ob_clean() there should be ob_end_clean() used. The first one doesn’t destroy output buffer, so for example if a theme also uses output buffering, it brakes ob stack. Also, if the function ends earlier (return in lines 415 and 418), the same error happens. It’s a common mistake.

Thanks.
