Clear mob spawners if the Java server so requests (#4232)

Browse source 
* Clear mob spawners if the Java server so requests

* Empty spawners by replacing the spawner block with a new one instead of adding an invalid identifier to them.
Unfortunately, sending one UpdateBlockPacket that replaces the spawner does not work, we need to set the spawner to air first. Cool. But at least we don't summon particles for all empty spawners now

* store position vector (address review by @konicai)

* remove empty line
