Added command /nickcolor - Allows players with the permission node hexnicks.changecolor (if use-permissions is set to true in the config!) to change the color of their name while blocking them from changing the name itself.

Examples:
/nickcolor &a --> makes the color green
/nickcolor #00FF00 --> makes the color green
/nickcolor &aMajek&4dor --> makes the color green and red!
^ Please note /nickcolor only accepts text other than color codes if it's the same as your name!
