Made the Menu not overflow when there's more items than the Window space (thanks, yetris)
Made possible for the Board to scroll on all 4 directions; crazy, right?
Added a global delay for when to make the Board scroll, beyb
Added settings for which direction to scroll the board
Made possible for the `MenuItemNumberbox` to jump within different units
Added option on the Main Menu to specify the scroll delay
Added options on the main menu to say which direction to scroll the board
