Redirects from www.reddit.com to corresponding old.reddit.com page
These are all versions of this script. Show only the versions where the code changed.
Added one more URL to not move to old Reddit from, because it also breaks.
do not redirect polls either, just like galleries are only on new, so are polls
Changed to not redirect gallery links since they result in error on old reddit.
Added greyscreen to let user know redirection is happening.
