Actual Teddit Redirect door Excalamus

The Actual Teddit Redirect add-on is based on the Teddit Redirect addon which would only redirect to Teddit *after* first going to Reddit. This add-on does the text replacement *before* the request is made so that Reddit is never contacted by you directly. (You can verify this by going to `Web Developer > Network` (Ctrl + Shift + E) and watching the network traffic when a request is sent.)
