Allow players to choose the color given to dogs' names

[HeroGamers]

Request by CABi_bakkit from SpigotMC.

Adding color codes to the dog's names (preferably keep the color code separate from the dog's name in the dog's data (dogs config file), so it's easier to change, and just input the color code from the dog's data when adding the name.

Ah wait shit, you can already color their nametags when you color the collar. Closing feature request.
