v9.2:

- improved mining speed stability.
- added changes in DCR mining protocol.
- fixed possible issue with rejected DCR shares on Nicehash pool.
- added pool selection in runtime ("e" and "d" keys).
- now if devfee mining fails for a long time, miner will not stop mining, it will turn on "-nofee" option temporarily with appropriate warnings, until successful devfee mining.
- some minor improvements.
- EthMan: added ReasonID parameter to .bat file which is executed when some rig has problems, check "sample.bat" for details.

NOTES:
1. Mining speed stability is better now, but still is not perfect. I'm working on it.
2. DCR: after changes in DCR mining protocol, both pool and mining software must be upgraded. At this moment the miner works with Suprnova, but fails with Nicehash, probably they will update their pool soon. Or may be they applied changes somehow differenty.
