Child Theme for my personal website at https://www.versluis.com, based on Automattic's TwentyThirteen theme.
- 21 different header images, changing randomly
- custom glowing font in the header
- auomatically adds the Apple Podcast Badge underneath posts in Podcast Categories (adjustable in /includes/podcast-badge.php)
- no JetPack upsell message in Admin Intrerface
