Subject: [PATCH] Fix Anvil Level sync to client

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/763827668e6e5cddc111f3c93a0d718fec21ff51

Was done incorrectly and is now causing level desyncs to client.

Always send current level to the client, and instead make setWindowProperty set the level.
