Added an in-game editor, which can be opened with command /cvteditor (requires customvillagertrades.command.editor permission to use). The editor allows you to create, edit, and delete custom trades.
The editor includes Blueprints which allows you to apply any trade you want to a villager by using RIGHT-CLICK on them with the corresponding trade blueprint.
Bug Fixes
When switching between trades that used money as an ingredient, the cost was being deducted from the players account without reimbursing the player for the previous trade's ingredient(s).
