Suggestions for V0.3

[xberg]

Thanks again for your great dashboard.
Here are some suggestions. All low priority but nice to have:

sort by column
Global stats:
CPU hash / GPU hash
share split GPU round / CPU Round (%)
hash / attempt for GPU round / CPU Round (the global hash / attempt makes little sense, mixing GPU and CPU)
block finds for GPU / CPU
Add a "Reset" link that resets all. (great when changing miner settings)
Potentially a reset link by miner as well. (so we can just reset one of a few miners, not all)

thanks!
