Cargo Containers: An alternative to crate hauling

[Alkheemist]

About the PR

Collaboration with @Temoffy and @blackknight954, adds

• A new system of tagging items with bonus value if they are on a grid docked to another grid tagged as a valid destination.
• New ships only purchasable at a special shipyard for purchasing shipping containers
• A receipt/voucher system to sell the new shipping containers
• New sprites for cargo pallets (shipping container fills)

Why / Balance

Turns cargo hauling from cratespam and dragging hell into an engineering challenge of having enough thrusters/docking points to haul more cargo.
