"Done" button in statistics screen is offset

The bug

The "Done" button in the statistics screen is offset. It would be expected to be centered, similar to the rest of the menus.

Fix

GuiStats.java

public void initButtons()
    {
--      this.buttonList.add(new GuiButton(0, this.width / 2 + 4, this.height - 28, 150, 20, I18n.format("gui.done")));
++  	this.buttonList.add(new GuiButton(0, this.width / 2 - 100, this.height - 27, I18n.format("gui.done")));

    	//...
    }

Before and after.
