Instead of checking pickaxe check if its not mobspawners

[provsalt]

Since you will need a mobspawner in your hand to add spawners,you should check if player is holding spawners

Spawner Stack size should be shown in the UI when the player taps the Spawner, not just while tapping the Spawner with another Spawner. This is useful in situations such as in-game raids where the raiders might need to check how much a Spawner is worth
