JoyRant build 18

I fixed a bug which would "break" links when editing a rant or a comment.

The links broke because devRant shortens them.
So now I’m "resolving" them by replacing the short links with the full links when editing.

Here I used the good old trick to start from the end and replace in reverse so that the ranges don’t get messed up with multiple links. 🙂
