Patch #4736 for Chessbox from Miguel A. Arévalo - Added support for user interaction while thinking, you can force move now with PLAY and quit with OFF (iRiver example). Yield only on Search as any Evaluate will be preceded by a Search. Plus some minor code policing from me to remove tabs in both the patch and the original code
