Poem new GPU app update

[Maxwell]

Notes on the new GPU app so far:
Project updater needed to get wus flowing
Only running on the R9 295x2, increased from 1 wu per r9 290x gpu to 2 wus per gpu and it took no more time. Double the credit same amount of time. Keeping about 4 cpu threads free for the 4 wus. Completing 4 wus every 2.25 hours (11,555 credits an hour, on collatz the card produces ~130,400/hr).
Usage is still less than 100% on the GPUs, I haven't tried 3 or more wus.
Power usage and heat are a lot less than collatz (not hard to do).

Thanks for the heads-up on this. I need to get back to Poem, and this'll be useful...
