[Feat] implement an ActionManager

[NekroDarkmoon]

Add a getter on the Item Document get actions () that returns an ActionManager class. This should be the default interface for interacting with actions on an item.

• Add a proxy to the ActionManager that allows for direct access to actions. actionManager.itemId
• Move all the action helpers from the base item class to the action manager.
• Allow for the ActionManager instance to be iterable. Object.entries(actionManager) or actionManager.
• [Feat] Add warning for actions system #59

Future improvements include sub managers for each action to easily get prompt data, Target data, roll data, and Consumers.
