Duplicate config options
i'm a bit confused about some duplicate config options in class hirachie.
For example if you look at Panel.
The Panel defines 'applyTo' as option.
Panel extends Container extends BoxComponent extends Component which itself defines 'applyTo' as config option.
The same can be seen with 'bubbleEvents' in Container.
Container extends BoxComponet extends Component which also defines 'bubbleEvents' itself.
Does someone now whats the matter with this?
