EchoTrace

Added a new config option to specify how many points to draw each cycle, allowing you to make traces that reach their target within a single tick if you wish. Can be set to 0 or -1 to draw as many points as needed to reach the target within the first tick, but don't do that in production! Particle effects and sounds are not thread-safe, so the tracing logic has to be run on your main server thread, freezing your entire server if too many points are drawn in one tick.

Fixed UpdateChecker not notifying the console when a new update is available.

Adjusted a few config descriptions and added a hint that makes sure you know the reload command exists.
