* TupleN extends ProductN, again (genprod updated)

* better comments and parameter names in scala.xml.MetaData typechecker
* now handles special cases (n=0, n=1) for unapply correctly

* * even if one returns a Option[Product1[T]]
* typechecker now handles unapply return types correctly
* * e.g. when returning Option[{A,B}] instead of Option[Product2[A,B]]
