Button now can handle middle and right clicks. Added 2 new handlers in button class: on_right_click for Right mouse button and on_middle_click for middle mouse button. Added functionality to vertically maximize window with middle mouse click on the maximize window button. Also added a way to vertically maximize window by resizing window height-wise lower than the maximum window height.
