* Hot-fix of memory issue. Engine hangs and throws OutOfMemory error after last memory tunings in version 1.1.1. Now it should work fine.
* Decreased trust window of MTD Search from 8 to 0. Now each iteration needs a bit more researches but on the other hand more transposition table's entries has 'exact' type.
* Enable the usage of transposition table's entries (their scores) also in PV nodes
* UCI: Fixed issue in 'setoption' UCI command. Sometimes Arena sends not only name-value pair but also additional information.
* Changed own opening book. The new one is based on Hitman 5.2.
