Mass Download Videos

First off, thanks for writing the script. It was a huge time saver!

I ended up adding a script that will loop through a directory of text files (each containing a url) and use the youtube-dl to download the video at the corresponding url. I created an IFTTT recipe to create the url text files whenever I add a new video to my "Watch Later" list. The recipe is here: https://ifttt.com/recipes/206234-youtube-watch-later-dropbox-url-file. I then added that script that script to a cron to be called alongside `php feed.php`
