Stagelock

Fixed: locked items added without marking the inventory changed, such as through /give or other mods, are now removed. Inventories are fully rechecked every 20 ticks by default (inventoryRescanTicks in the server config).
Fixed: when several rules lock the same item, the strictest one now applies, instead of whichever rule loaded first. Holding: destroy beats drop, and drop beats allow. Recipe viewers: hide beats lock, and lock beats show.
Changed: messages, tooltips and hidden names now come from the rule that actually decides the outcome.
Improved: /stagelock why now shows which rule decides each action.
