Removes redirect on outbound links.
Reddit users are tracked using a redirect (similar to google) where the url is replaced when you click the link. Users with accounts can turn this tracking off in their settings, but that doesn't help when logged out.
Note that Reddit still knows:
This script is for users who hate waiting on the redirect, if you think this script "saves your privacy" then you are kidding yourself.
The origional author of this script is /u/ItsMeCaptainMurphy who posted it here. His version doesn't check links fetched after the pages loads however.
