Allow API to bypass "Do you want to add these items to your character sheet?" prompts

As a module developer, when I run this:

game.actors.get("<player actor ID>").createEmbeddedDocuments(
	"Item",
	[
		{
			name: "Barbarian",
			type: "class",
			data: {
				levels: 20,
			},
		},
	],
);

I do not want the user to be prompted to add class features. In general, a flag to disable "unexpected" side-effects such as this, would be a great improvement to the API.

---

Implemented with the following options on createEmbeddedDocuments:

{
  addFeatures?: boolean; // if set to `false` short circuts the whole feature application flow
  promptAddFeatures?: boolean; // if set to `false` skips the prompt and simply adds the features as 1.2.4 does today
}
