v3.16.0

Minor Changes

• Users now have the ability to select which extractors are used during a download session.
• Users can now choose to add a user or subreddit to a list without validating their existence with reddit first.

Bug Fixes

• Files that are under 1KB in size are no longer downloaded. This should keep deleted content placeholder images from
  being downloaded.
• Fix crashing when copying a user/subreddit to another list.
