Pack It Up!

Changes

• The lunchpack and plantpack are now based directly off the backpack and are made using iron blocks. If I need to balance this with for example slot count, I will.
• Textures for these two packs have been updated to an iron coloring.
• Bag recipes updated with Iron blocks.
• The large backpack is now craftable from any of backpack, lunchpack, plantpack.

Fixes

• Fixed potential crash if a player swaps from a pack with more slots to one with fewer.
• Fixed some lang file issues.
• Fixed the pack bench swallowing itemstacks rather than giving them back to the player if you close while items are in the bench.
