Casual - Mix between Checkbox and Radio buttons

The Casual screen lets the player select from the four game modes (Defuse, 3 Site Defuse, Hostage and Assassin) or random, which picks a random one, essentially selecting them all at once but providing an easy and intuitive way to do so. I don't want Random and a game mode to be able to be selected at the same time however, so I created a way to deselect the random button if a game mode button is selected, and to deselect the game mode buttons if the random button is selected, but only doing so if they are selected.
