* Add a container around the tabs and use flexbox
to position the tabs on one line and make it
scrollable.
* Add some JS to scroll the currently selected
tab into view.

Even though on most pages the tagline is empty, it still
has a bottom margin associated with it. This patch moves
that bottom margin into a container element that wraps
both the h1 and tagline.
This approach allows us to remove the bottom-margin from the tagline
as well as the top-margin from the AMC tabs in favour of just
one bottom margin on the .page-heading element.

A new feature/skin option is added that is enabled safely inside
a MobileFrontend available/unavailable hook that changes the skin
to place talk tabs at the top of the page.
These new talk tabs purposely show on the main page, user page
and standard pages and do not show on special pages.
