Marco Trevisan (Treviño) c4c5c4fd5c cleanup: Use inheritance for Actor classes instead of composition
Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.

Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.
