Subject: [PATCH] Update clients when setting blocks to air
In fixing SPIGOT-611, the server sets an area to air and doesn't update the clients.
Usually this is fine, most of the time we'll just be setting the intended block shortly after anyway.
Except if we're setting air. In which case the server will not send the change because it already sees the block as set.
We workaround this by telling the server to send the client the block change if it is of ID 0 (Air). I assume this
patch will not last long enough to warrant moving away from the ID.
