Updated Ruby Exception handling. Classes that are specified in throws clauses, or are marked as %exceptionclass, are now inherited from rb_eRuntimeError. This allows instances of these classes to be returned to Ruby as exceptions. Thus if a C++ method throws an instance of MyException, the calling Ruby method will get back a MyException object. To see an example, look at ruby/examples/exception_class.
