PHP Warnings cluttering error log

Thank you for this plugin. While it continued working, two conditions triggered warnings.

1. When WP’s own twentytwentyone theme’s 404.php was used.
2. When updating any post/page, after clearing the check box to unhide its title.

Warning case #1:
Attempt to read property "post_title" on null in .../hide-page-and-post-title.php on line 90
Warning case #2:
Undefined array key "hpt_headertitle" in .../hide-page-and-post-title.php on line 102

Suggested hack case #1. $post == NULL. Replace the line (was 90):
$this->title = $post->post_title;
with this test of the $post var using ‘instanceof’

	//$this->title = $post->post_title;
	if ($post instanceof WP_Post) {
    		$this->title = $post->post_title;
	}

Whenever $post is not a WP_Post object, skip trying to read the title property.

Suggested hack case #2. Replaced the line (was around 102):
$new = $_POST[ $this->hpt_slug ] ;
with this test of the $_POST key

	//$new = $_POST[ $this->hpt_slug ] ;
	$new = isset( $_POST[ $this->hpt_slug ] ) ? $_POST[ $this->hpt_slug ] : NULL;

Silence is golden.
