Custom action example not complete

[lab101]

I had some issues making a custom action.
When you use the code from the example in the documentation there's a promise error after the apply.

There should be return Promise.resolve (); in the apply in order to make the example work.

Well, the engine seems to be long dead. I've managed to make my custom actions work, though.

In case someone finds this issue, the real custom action example should be more like:

class MyAction extends Monogatari.Action {

    static matchString ([action]) {
        return action === 'myaction';
    }

    constructor ([myaction, ...args]) {
        super ();
    }
    
    async apply() {
  
    }

    async revert() {
  
    }

    async didApply() {
      return { advance: true };
    }

    async didRevert() {
      return { advance: true, step: true };
    }
}

MyAction.id = 'MyAction';

Yes, you do need the didApply and didRevert boilerplate, or rewind won't work.
