When trying to run the miner in benchmark mode it seems to ignore the algo parameter (it's always trying to bench blakecoin and fail).
Please fix by either wiring up the algo passed in as a parameter, or hardcode lyra2z instead of blakecoin.

Reproducible by running: coolMiner-x64 --algo=lyra2z --benchmark --time-limit 20

I'm trying to plug this miner into my GUI:

And benchmarking is a crucial functionality needed to make it work.

Thanks.
