This doesn't let you arbitrarily call back into the VM from within foreign methods. I'm still not sure if that's even a good idea since God knows what that would mean if you switch fibers while doing that. But this does allow the very important use case of being able to call a foreign method from within a call to wrenCall(). In other words, foreign methods need to always be leaf calls on the call stack, but the root of that stack can now come from runInterpreter() or wrenCall(). Fix #510.
