Player inventory configuration

[osipxd]

There should be possibility to customise player inventory slots:

• Storage slots
• Hotbar slots
• Equipment slots
• Craft slots

Possible config format:

player-inventory {
  equipment-slots {
    head: [slot-id]
    chest: [slot-id]
    legs: [slot-id]
    feet: [slot-id]
    off-hand: [slot-id]
  }
  craft-slots {
    0-4: [slot-id]
  }
  storage-slots {
    default: [slot-id]
    0-26: [slot-id]
  }
  hotbar-slots {
    0-8: [slot-id]
  }
}

If slot is not configured it should use default vanilla behavior.
