Version 0.0.21 beta:

- New: Thumbnails for some services (currently supports: YouTube.com, dailymotion.com, vimeo.com (slow!) and imgur.com). Thumbnails are enabled by default, but you can turn them off (set define('ENABLE_THUMBNAILS',true); to false.)
- Changed: Removed the focus on the searchbox (this is cumbersome when you want to browse pages and scroll with the keyboard).
