Subject: [PATCH] Option to use vanilla per-world scoreboard coloring on names

This change is basically a bandaid to fix CB's complete and utter lack
of support for vanilla scoreboard name modifications.

In the future, finding a way to merge the vanilla expectations in with
bukkit's concept of a display name would be preferable. There was a PR
for this on CB at one point but I can't find it. We may need to do this
ourselves at some point in the future.
