LibChess+ChessEngine: Don't crash on error when reading UCI commands
ChessEngine and the chess GUI will no longer crash on error while reading UCI commands. ChessEngine will print a message to the standard output, while the GUI will ignore unknown commands. Both will print the error to the debug log if the UCI_DEBUG flag is enabled. Trailing and preceding whitespace is now stripped from commands before they are parsed. Commands which are just whitespace no longer produce errors.
