- Navigation header array structure now is the same as the structure of the navigation menu array

- Implemented the sort logic and added the "sort" attribute to sort menu and header entries for the NavigationWidget
- Added the private method _sortArray to the NavigationLib to sort menu and header entries
- Added the "target" attribute to be used with the attribute "link" to build the link of a menu or header entry
- Now the header menu supports icons on the left side of the entry description
