    Derive Typable for promoted data constructors (Trac #8950)
    
    I got sucked into a significant refactoring of the way that
    Typeable instances are derived.  This makes it simpler and
    more uniform.
    
    I also improved the documentation in the user manual.  Typeable
    really is different to other classes, and now gets its own subsection.
