Splitting up the article view as a subtask to do the following:
- Move 'add to reading list' and 'share' as more common actions users can take to the top toolbar
- Place all article actions into an overflow menu in the top article toolbar
- History (aka Recently read) is moved as a sub-section within the article overflow menu
See mocks at details in context on the main ticket.
