  Log:
  	Fix what "standard class" means
  
  	MERGE to STABLE
  
  The Report's definition of defaulting (Section 4.3.4) defines a "standard class" to be
  one defined by the Prelude or a standard library.  GHC was omitting the "..or a standard
  library" part; and it even omitted the Prelude classes Monad and Functor.
  This commit fixes the bug by adding
  
  	Random, RandomGen,
  	Monad, MonadPlus, Functor
  
  to the classes defined as "standard".
