It adds support for zcoin lyra2 using either "-a zcoin" or "-a lyra2z". Lyra2RE (lyra2) and lyra2REv2 (lyra2v2)
still work as usual.

Although I have optimixed it for AVX2 there was no observable change in performance in my testing.
I suspect the algo is I/O bound meaning the CPU spends a lot of time waiting on data from memory.
LGA2011 systems with 4 channel DDR may do better. Feedback is appreciated.

The diff display for cryptonight in the API has been fixed.

Changes in diff will now be displayed by default (--show-diff). Use "--hide-diff" to disable.

Removed some cpuminer-multi artifacts.

I am considering dropping the btver1 build from the Windows binaries package. Before I do so I would like to
know if anyone is using it and whether it performs better on an AMD CPU than any of the Intel builds. The
btver1 build does not include any optimizartions so is not suitable for recent AMD CPUs.
