AstroBWT miner astrominer V1.9.2.R3

V1.9.2 CHANGE LOG:

• Minor optimization, 2->3%
• modern and generic are now in a single file.
• Make way for a huge change in V2.0
• Auto switch to main node when it goes back online. (Behavior: when main node (-r) goes offline, astrominer switches to the first failover node (-r1). At this point, the miner will check the connection to main node every 5 minutes. If it goes back online, astrominer will switch to the main node automatically.)

Introducing new features:

• param -ft to select the fine tune kernel (-1(auto select), 1(low, mid-end CPUs) or 2(high-end CPUs)). Dev note: The miner usually pick the right kernel for you, but in some corner cases or under some OC situations, it's better that you pick this param for your rigs.
• param -zero-hr-restart-time Time (in second), restart (or exit if the watchdog is disabled) the miner after being zero hashrate for a while (default: 120 seconds, set -1 to disable) Dev note: this feature is very useful for large mining farms, or miners that stay under weak stressful internet line.
