0.17.2
* Add "ethash" algorithm (for Ethereum). For Nicehash mining use "nicehash+tcp://" pool url prefix.
* Add "progpowz" algorithm (for Zano)
* Add "--pci-indexing" parameter: orders GPUs by PCI Bus Id (same as "--ab-indexing" but starts with 0)
* Add "--gpu-init-mode" parameter: enables sequential DAG generation to reduce load on power supplies
* Print hash rate if no shares have been found for more than 1 minute to indicate miner's activity

Bug fixes:
* CUDA 11 build not working on some algorithms (x25x and similar), and with RTX cards
* "GPU is idle" error when generating DAG on low-end cards
* "nan(ind)" in share rejection GPU stats
* Log files not rotated correctly
