Adds landmarks to the article toolbar
- Namespace navigation
- View navigation
- More options navigation
Removes the "tools" landmark and associated
aria-label (and translation message).
Makes the #left-navigation and #right-navigation
flexbox to ensure the new <nav> elements, along with
gadgets, align on one line. Moves the styles for
these elements from screen.less to ArticleToolbar.less.
