Farrago v1.0 Pre-Release 7

Another pre-release because I have one-point-oh-phobia.

Changes since v1.0 Pre-Release 4:

• Partial impl of the Cell Filler
• Add Yttric Copper Utility Belt
• Add the ability to 'lock' Utility Belt slots
• Make the Utility Belt drop all items it's holding when it breaks
• Increase the durability of the Utility Belt
• New default controls for the Utility Belt; +, -, 0, and backspace
• Add the ability to disable Gunpowder and Arrow Kahur special behaviors in the config
