Add doc header to Dynamic's re-export of Typeable
Add doc header to Dynamic's re-export of Typeable

Data.Data and Data.Dynamic both re-export Data.Typeable with the same
comment, though in the Data module the comment is a haddock header, and
in Typeable it is not. I assume the inconsistency was a mistake.
