Block Breaker should pause if inventory is full instead of dropping items

[maradotwebp]

Current Behaviour: If a block breaker has a full inventory, blocks are still being broken, but they spawn as drops.

Proposed behaviour: If a block breaker has a full inventory, the block breaker skips the action and does not consume energy.

Why?

• would make automation easier
• would make behaviour consistent with vanilla (furnaces also don't start spewing items everywhere if the output slot is full)
• would make behaviour consistent with the block placer (it pauses if it can't place a block)
• would prevent my concrete farm from generating about 1k item drops per minute while I'm afk and blissfully unaware of the chaos unfolding around me
