When doing donations, I noticed that if I typo the name when doing a cp listperms, even if its just a case-sensitive issue, it creates the user with the incorrect spelling, and then i can't modify the one with the correct case-sensitive syntax

I also need to be able to delete users from the console / in-game, or the ability to lock the users.yml file, edit it, then load it

per issue #10, auto-complete would be wondrous in resolving this if its easy to do

adding users as typo's was fixed with #10. /cp delete was added with 378423b
