Buy / Sell items

[alvinl]

Implement a way to have the bot buy / sell items at a price configured in the config.

Example config:

{

  "items": {
      "item name": {
        "buy": 6.11,
        "sell": 6.33
      },
      "holy mackeral": {
        "buy": 0.11,
        "sell": 3
      }
  }

}

• The way this is configured in the config is up for debate. I'll update this issue with any updates
