Fix throw opcode, make fizmo work for the Dialog sanity checks.

This fixes games written with the Dialog system. See:

Fixes compile-time error.

I tried building after a `./configure --disable-output-history`, and
discovered that there was one (but only one!) reference to some
undefined output history resources.  With the `#ifndef` protection
added, it compiled and linked successfully.
