OneZeroMiner 1.5.2

Changelog

Qubitcoin:

• Added a new kernel for CMP cards with nerfed f32/f64 performance (--kernel 2).
• Performance improvement for the other cards

Note: Miner should pick the best kernel by itself but if you have a cmp card with relatively poor performance, try --kernel 2. Default is kernel 1 for all other cards.
