Extend (add extended features) Navigation Block

[VitaliiDC8]

1. We need to have access to all components from 'NavigationItem' dir, by this way developer can create own component which will be wrapper of those navigation items for desktop and mobile layout or just extended component. We need it, beacuse your components are using analytics and we don't want to create this again for wrap component.

2. To support style for active menu item by route path

3. It would be nice to have a feature to change layout menu (i.e. menu items should be after logo on the second row or another way). Having configurable menu layout would be usefull for desktop and mobile version.
