Inventory_Crates

NEW: Seal / Unseal crates - New action "Seal crate": locks the crate and packs its contents to reduce server load - New action "Unseal crate (X items)": unpacks everything back into the crate - Simple items (full magazines, bandages, grenades, tools etc.) are stored as data while sealed instead of as individual objects – a sealed crate with 50 items costs about as much performance as a single item - Items that would lose information (partly used magazines, damaged items, backpacks, vests) stay in the crate unchanged - A crate can always be sealed, even if none of its items can be packed CHANGES: - Sealed crates are locked: "Open crate" is hidden and nothing can be taken out or put in until the crate is unsealed - Sealed crates can still be picked up, carried and loaded into vehicles WHY: At a recent server event, vehicles full of items caused heavy lag and FPS drops. Every stored item is its own object the server has to manage and send to players. Sealing crates before loading them into vehicles should reduce this a lot. KNOWN LIMITATIONS: - Seal and unseal only work while the crate is on the ground - Sealed crates weigh less, because packed items are not counted towards the weight - Sealed contents do not survive a server restart
