A fix for PHP 5.4 warnings empty value

When saving a Timeline entry I got multiple: Warning: Creating default object from empty value in… etcetera, on a blank page. This was with a new install (v. 1.1.1) on a server new to me. After googling on the issue I managed to fix it in wp-veriteco-timeline.php. Find:

if ($thumbnail_image && isset($thumbnail_image)) {
	$this->asset->media = $img[0];
	$this->asset->caption = $thumbnail_image->post_excerpt;
}

Replace this with:

if ($thumbnail_image && isset($thumbnail_image)) {
	if (!is_object($this->asset)) {
		$this->asset = new stdClass;
	}
	$this->asset->media = $img[0];
	$this->asset->caption = $thumbnail_image->post_excerpt;
}

I suppose you have to do the same with the next lines for video. And maybe more, but I have to find that out yet.
