Complete fix overbright issue in FF Type-0

Issue #1410

[unknownbrackets]

@raven02 if you remove this, does the problem come back? I was trying to repro in the demo and it doesn't seem to happen now. I read on the forum someone saying this was causing problems in some other game.

Another thing to try is:

Core/CoreTiming.cpp

void ScheduleEvent(s64 cyclesIntoFuture, int event_type, u64 userdata)
{
    Event *ne = GetNewEvent();
    ne->userdata = userdata;
    ne->type = event_type;
    ne->time = GetTicks() + cyclesIntoFuture;
    AddEventToQueue(ne);

    if (currentMIPS->downcount > cyclesIntoFuture)
        currentMIPS->downcount = cyclesIntoFuture;
}
