[DONE] Groups and permissions refactor

[AntherusCraft]

I mean there would be 2 groups, the permission-group and the rank iteself. So you can list permission-groups instead of extending another rank, that was my point. I'm still confused because of the "Player:" thing... Wouldn't it be easier to just make 2 lists like so: http://pastebin.com/rqFL1AX6 ?
