Subject: Adding emitComponentCompleteSignalForAttachedProperty()

Each item that is created by a component gets the
attached property "Component".
This property has the signal onCompleted.

This function allows the designer to manually emit this
signal once the item is setup.

I had to export QQmlComponentAttached for this.
