_NPN_IntFromIdentifier is wrong

int32_t _NPN_IntFromIdentifier(NPIdentifier identifier)
{
    PrivateIdentifier* i = (PrivateIdentifier*)identifier;
    if (!i->isString)
        return 0;
    return i->value.number;
}


The check should be if (i->isString) instead of !i->isString

This is a one line fix.  The test case is the PITA.

I don't think I got the test case quite right, debugging now.  I'm posting this now to make sure it doesn't get forgotten.

In order to maintain my sanity, I had to clean up PluginObject a little as well.  I did not make any attempt to further validate our NPNetscapeFuncs struct, it's possible we're still missing other function pointers.
