Xiphos 0.1

Github: https://github.com/milostatarevic/xiphos
Binaries: https://github.com/milostatarevic/xiphos/releases

Please note that the project is still work in progress. The evaluation function is relatively simple (~200 lines of code), and together with some other parts, can be further improved.

Regarding the strength, it should be on par with engines rated around 3000 Elo on CCRL 40/4 scale. I compared it only to a few other engines, so this could be off.

Xiphos 0.2
https://github.com/milostatarevic/xiphos/releases

Some features:
- improved evaluation
- singular extensions
- slightly faster search
- fixed time control issues
- no-popcnt build
- various other fixes

The new version is about 45 elo stronger than 0.1 in self play (tc=40/90s). When an incremental time control is used an additional gain of 20-30 elo is expected (due to the time allocation bug in version 0.1).
