In this release

Skip Null move pruning for moves that were in a previous PV
Increase reduction during Reduced depth search (LMR) if the move is found in the experience file
Automatic management of Full Depth Analysis when doing infinite analysis or finding mate. This option proved to be a great one for problem solving
Enable UCI_ShowWDL option which allows the GUI to control if Eman will show winning percentage or evaluation. Default is disabled
Fix polyglot book reading when book file size is more than 2GB (Thanks to H. Pieters for reporting this problem and providing me with sample BIN books, and for helping me reproduce the problem)
Change Polyglot book parameter names from Book 1 and Book 2 to Book 1 File and Book 2 File. This change will make some GUI's such as Arena and probably Aquarium show a [Browse] button to select the book file which is more convenient to the user.
Merge with all latest Stockfish updates from the development branch
