BNFC should generate IsString instances for Ident all the user-defined token types.

That would make it easier to build trees when using BNFC to generate pretty printers for code generation.

[#192] Haskell: Generate IsString instances for token types
f58014a 
The newtype created for Ident and user-defined tokens are now instances
of IsString. This makes it easier to build tree if you want to use
bnfc's pretty printer for code generation.

I fixed this afresh, not using the existing solution #284, which does not merge reasonably any more.
