[Plugin: Heatmap Plugin] WP-Subdomains and Heat Map Plugin

To make this work with WP-Subdomains, open up heatmap.php and replace the heatmap_set_wpurl() function with the following (tested by Peter):

/**
 * Function set domain name
 */
function heatmap_set_wpurl() {
	if(defined('WPS_VERSION')) {
		// WP-Subdomains installed
		$wpURL = 'http://'.$_SERVER['HTTP_HOST'];
	}
	else {
		$wpURL = get_bloginfo('wpurl');
	}
	echo "<script type=\"text/javascript\">\n//<![CDATA[ \n\tvar WPURL = '$wpURL';\n //]]>\n</script>";
}
