SUQA info
Added SUQA but it looks like the recorded hashrate is quite a ways off.  Doing the math it appears it needs about a 175 multiplier, is that correct?

I tried to add "hashrateMultiplier": 175, to my coin config but it didn't seem to do anything to the reported hashrate.  I seem to remember something about multiplier being removed but can't remember if it was hashrateMultiplier or not.

Also, does this look correct for the coin config?
