+Subject: [PATCH] Add CrafterCraftEvent
+
+Ports the currently proposed CrafterCraftEvent
+from upstream.
+The type is experimental to account for spigot
+potentially changing some api contracts, however
+the event is required for a stable release and
+waiting on spigot's PR queue is not an option.
+
+See: https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/pull-requests/1044/overview
