Adds 4 new Repair Packs!

• Copper Repair Pack (alternative to the normal Repair Pack but made with 4 copper plates instead of iron gears)
• Steel Repair Pack (slower speed but more durability)
• Field/Plastic Repair Pack (2x faster as normal repair packs, but they break more often)
• The Multitool (expensive but worth it)
