[Plugin: Paginated Gallery] WP_DEBUG notices

When WP_DEBUG is enabled, activating this plugin causes any page with galleries to get some debug notices shown eg:

Notice: Undefined index: galleryPage in .../wp-content/plugins/paginated-gallery/paginated-gallery.php on line 104

Notice: Undefined index: id in .../wp-content/plugins/paginated-gallery/paginated-gallery.php on line 138

replace line 104

$currentPage = intval($_GET['galleryPage']);

with

if (isset($_GET ['galleryPage'])) {
	$currentPage = intval($_GET ['galleryPage']);
	}

replace line 138

$id = $options['id'];

with

$id = intval( isset ($options['id']) );

These changes seem to fix the notices
