manuals: simplify references to classes

Now that .bbclass is removed from class section titles.
We can now have, for example, :ref:`ref-classes-insane`
instead of :ref:`insane <ref-classes-insane>`.

Then, when necessary, rework paragraphs so that they
have lines of even length, not exceeding 80 characters.
