Subject: [PATCH] Configurable BlockPhysicsEvent

Bukkit's BlockPhysicsEvent is *ridiculously* spammy and can easily rack in 1,600 calls/sec on a server with just one player. This hogs a ton of CPU time.
Paper does alleviate this quite well by only firing if plugins are listening, but a lot of common world protection plugins use this event do not offer toggles for their listeners, which makes Paper's change ineffective for most servers.
This patch implements a hard toggle for the event.
