PortaSpawner

The PortaSpawner is a MineFactory Reloaded item that allows the player to pick up and drop a worldgen spawner. By holding this item, the player may right-click on any type of spawner and it will add a tooltip to the item saying what mob spawner is inside. To place it back down, simply right-click with this item and it will place the spawner, destroying the item in the process.
