+Subject: [PATCH] BlockDestroyEvent
+
+Adds an event for when the server is going to destroy a current block,
+potentially causing it to drop. This event can be cancelled to avoid
+the block destruction, such as preventing signs from popping when
+floating in the air.
+
+This can replace many uses of BlockPhysicsEvent
