Pressurized Spawner

A Pressurized Spawner/$ is a powerful device which uses pressure/$ to spawn mobs. It doesn't care about light levels or player proximity, and can be enabled/disabled via redstone. To use a Pressurized Spawner, you will need a Spawner Core/$ containing some captured mob essence, and at least 10 bar of pressure. When a Core contains multiple mob essences, a random mob will be picked. E.g. if your Core is 50% zombie, 25% creeper, and 25% empty, then on each spawn attempt, you have a 50% chance of a zombie, 25% for a creeper, and 25% for nothing at all. Air is still used if nothing spawns, so partially empty Cores are not very efficient (but then again, a Core with a 50% chance of a rare mob is better than no Core at all...)
