/Rename is a different command all together. And to be honest. Im compleatly new to the whole thing. It just happens i have been messing around with this for a few weeks. Just as a past time. And when you made this post. It just so happened i had already added all of the commands requested. Other than the rename command.
Although i will say I can add it to 1.5.9. I noticed that was released just last night thats why i had stated in the post i used 1.5.8.
And lm not sure about the plugins all together sorry. Like i said my experiance is not that experianced:D
