So finally got around to rolling phoenix2 into BAMT.  It seems to work great, nice job.

I thought originally we'd have to write a plugin, but actually the RPC interface does everything needed except a couple statistics, and I think those are simple to add.

Right now it reports 'results' per GPU but not accepted vs rejected, and not shares that are discarded as stale or if the "Result didn't meet full difficulty, not sending" condition in KernelInterface happens.

I added simple counters for these and then included them in the results of listdevices, just like 'results' is done.  Seems to work fine though I am not sure it's the best way.  Could these types of status be added to the official rpc interface?
