Implement Firework.detonate(). Adds BUKKIT-4538

This implements the detonate method from bukkit by setting the fuse
timer to 0. This makes a firework explode using the normal codepath,
but without waiting for the fuse.
Follow vanilla settings behavior. Fixes BUKKIT-5069

A vanilla server does a series of checks for the client black-listing
certain chat types (commands or chat). This change changes a CB
whitelist to the vanilla blacklist behavior.
