Remove JavaScript that collapses tabs and replace with an easier to maintain breakpoint based solution. Tabs will now collapse below the tablet breakpoint Note: In the case of mw.util.addPortletLink, to add items to the `views` menu, these will not be collapsed into the more menu and must now be explicitly added to both menus, ie. if the window is resized these will hide and not appear in the more menu. However, when mw.util.addPortletLink attempts to add to `views` menu when there is not available space, we will redirect those links to the more (`cactions`) dropdown menu.
