Beans Backpacks

• Backpacks are now visible in Smithing Screen
• Leather Backpacks are now more colorful and look closer to their item's color
• Added the option to rebind the key to place Backpacks and move items.
• Hovering over the rebind option explains how it works.
• Empty and equipped Backpacks now display text on how to move items in inventory instead of an empty backpack inventory.
• Added a bar on equipped backpacks that display how full its inventory is.

Big thanks to ApionXD for his suggestions. :)
