Trigger Block / Tile Entity update

when eventTileEntity set given area is called it then places trigger
blocks at the given area , only if it is a air block at that position.
Then checks to see if a tile entity exists as well, if so setEventPos()
is called and pushed to the client / server.

trigger GUI got a new feature that checks the setX, Y and Z of the
trigger with the world to see if the event exists. If so then it is set
and green else not set and red.
