Time for action – modify Game1 to generate rotating pieces

Update the HandleMouseInput() method in the Game1 class to add rotating pieces to the board by adding the following inside the "if mouseInfo.LeftButton = ButtonState.Pressed" block, before _gameBoard.RotatePiece() is called:
```
_gameBoard.AddRotatingPiece(x, y,
    _gameBoard.GetSquare(x, y), False)
```
Still in HandleMouseInput(), add the following in the same location inside the if block for the right-mouse button:
```
_gameBoard.AddRotatingPiece(x, y,
    _gameBoard.GetSquare(x, y), True)
```

What just happened?

Recall that the only difference between a clockwise rotation and a counter-clockwise rotation (from the standpoint of the AddRotatingPiece() method) is a true or false in the final parameter. Depending on which button is clicked, we simply add the current square (before it gets rotated, otherwise the starting point for the animation would be the final position) and true for right-mouse clicks or false for left-mouse clicks.

Calling UpdateAnimatedPieces()

In order for the UpdateAnimatedPieces() method of the GameBoard class to run, the game's Update() method needs to be modified to call it.
