Delete or modify users from administration menu

[nojux-official]

I wanted to change the ram limit of the user server, but I couldn't find how to adjust the user data through the administration menu. I later wanted to delete that user, but I also couldn’t find where. Finally, I found that I could change the user data in the data /users/ folder. I think it would be good to add these functions to the administration menu, so it would be easier to administer users.
