Command handlers that return values

[NickSeagull]

In this release we introduce the @Returns decorator that allows you to define the return type of a command handler.

This value will be returned to the client through GraphQL, instead of just returning true (that's left for the case of void).

As an example:

@Command({
  authorize: 'all',
})
export class CreateProduct {
  public constructor(readonly sku: string, readonly price: number) {}

  @Returns(String)
  public static async handle(command: CreateProduct, register: Register): Promise<string> {
    return "Product created!"
  }
}
