In I23f18fc5f078da3331cad540bbaf533d348f2108 layout was pulled out
into a separate file and we changed the ordering of our CSS.
This was done with the thinking that media print queries would be
mixed with media screen.
After discussions with Volker, I have been convinced this was a
mistake.
media queries of the same type can be nested so the @media screen
is removed from layout.less and the media query in index.less will
be used instead.

Does not add `.mw-footer-*` CSS classes to `ul#footer-*` and
`li#footer-*-*` to save bandwidth.
NOTE:
- The former id selectors can be removed form the styles after the varnish cache
is updated with the new DOM.
- The modern version still uses the legacy layout at this stage.

Going into the new version of Vector, we'll want to rewrite the layout
rules entirely and decouple the sidebar from the logo.
To prepare for this we will move the layout file into a legacy folder.
We also separate Sidebar styles needed for the legacy mode from the old mode.
This will allow us to make changes to the header in new Vector without having to touch
or test the legacy codebase via a new file layout.less and using the existing sidebar
code.
