add remainderWindowOpen to give immediate packets a better chance

[habazut]

Pull request so that we do not forget to improve packet handling. Yet untested.

[Asbelos]

Window needs to be opened a little earlier otherwise the waveform will start an idle packet before the loop gets the chance to inject a reminder.

[FrightRisk]

So where does this fit now with the changes that have been made since this was issued?

[Asbelos]

Recent changes dont really affect this.
Basically the waveform needs to change slightly to move the preamble to the END of the packet and set a flag indicating that its close to the end of the preamble.
Reminder loop should not schedule a reminder packet unless the flag is set.
Anyone who complains that the preamble should be at the start... isn't thinking hard enough.
