Add support for LinkButtons in get_component_classes

[benbjohnson]

LinkButton is a subclass of Button. The thinking behind excluding LinkButton was that when you're specify a feature the end user would specify something as simply a "button" and not necessarily know that it should be called a "link button".

Do you need to specifically retrieve a "link button"?

If I say "button", will it find all components which are of a type that subclasses Button as well? I'm curious because I have a number of custom control classes. I've been looking them up by their explicit classname because I didn't think Melomel would find them otherwise.

[benbjohnson]

Yes, Melomel will pick up any subclasses of the Halo or Spark Button when you specify "button". The comparison inside Melomel just does this:

if(displayObject is classRef) {
  return true;
}

There's actually no way (right now) to specify Melomel to find a Button but not a subclass of Button.

Awesome!
