FWH count as negative IBU #138

When the FWH time is set (according to the preferences) the tool should detect it as a first wort hop and adjust the efficiencies appropriately.

According to the math I can find, it improves all efficiencies by 10% for additions. But I need to find out what the efficiency is on the FWH themselves...

Reading around, it looks like FWH usage is the same as adding in at 2/3rd (65%ish) of the boil time.

So for a 60 min boil, it's the same efficiency as 20min. 90min boil = 30min addition utilization.

I'll add this in with a customizable preference for the % improvement and equivilent boil time.
