Unbranding / copyright removal

I can remove the main copyright notice, that's ok, but I want to remove all "babble" mentions.

F.e. via friendly URL rewrite settings I can change the babble directory for the standard room. So far so good.

But if I enter another room with the room--?? command, it forces to use the standard /babble directory path.

Also in some situations with the time bot or the count bot, the bot message sender is sometimes "babble"
