Update python_easy_chess_gui.py

* In polyglot column header, change weight to score. Polyglot move scoring on book building is 2 points for a win and 0.5 point for a draw.
* When user presses Set Engine or Set Book, it will create a new window and hide the main window so that user cannot interact with it. But this time main window is not hidden and any interaction to the main window will be ignored.
