[API] Device total hashrates please....
First off thanks for all the hard work you put into this miner. I'm currently working on an implementation on EthOS and am facing challenges when trying to get gpu hashrates from your miner.  I would love you forever if you would add device totals to the json api. Please...it just doesn't seem practical in any other way. I've mentioned this on the xmr-stak github before but the devs didnt seem receptive.  Again, please, this would one-up you on those guys. :)

Thanks again and keep up the great work.
