- Fixed bug where YouTube changed "Video unavailable" HTML text element from having class name 'reason' to now having id 'reason'. It wasn't skipping the videos because of this.
- Uploaded new screenshots/media to illustrate completely new UI
- Changed how songs were randomized. Before, a random song index would be generated at each iteration. Now, all songs are shuffled beforehand and we just choose the song at the 0th index.

v2.3.4 - Fixed bug with empty playlist error message where if a user entered nothing and began a playlist, the error message would not pop up.

v2.3.3 - Fixed bug in Firefox where clicking on playlist insert and delete buttons did nothing. Also manually added fonts to replace default fonts for all error messages.

v2.3.2 - Fixed bug where "No recent playlists" text was not showing up.

v2.3.1 - Fixed bug where "No recent playlists" text was not showing up. Also removed https://apis.google.com from content security policy, since we no longer rely on the YouTube API.

- Added error messages when a user tries to begin a playlist that contains 0 YouTube links
- Added functionality to store the 5 most recent playlists the user used
