Doc: Add sidebar content used in the qt.io online template

As part of the new online style, each page has a sidebar with
links to common topics - the same content as on the Qt reference
documentation (index) page.

Switch the order of the topics on the sidebar, based on Google
Analytics feedback. Most-used links are from the 'Reference'
category, so raise that one to the top.

This commit adds the raw .html file into /style, which is then
loaded dynamically by the template code.

Doc: Change the div classes for three-column layout

The new documentation style for publishing docs under qt.io
requires dedicated div classes for pages that use a three-
column layout.

The new divs enable the columns to stack and react to changes
in the window width.
