This is a bugfixes only update:
* Signs on the sides of cacti no longer crash the game
* The player won’t get stuck on the top of the world in multiplayer
* Reverted mob spawning back to the old code, it was far to annoying. I have plans on what to do with this.
* Fixed the leaf particle colors
* Reduced CPU usage for monster spawning, but there’s still a lot of work to be done to reduce lag on SMP servers.
* Attempted to fix the portal dupe bug where you could exit through a different (new) one than the one you entered through.
