System to handle the main menu button actions

• interaction_query: grabs all the buttons that have been interacted with, with the components Interaction and ButtonAction that have a changed interaction value (i.e. the button has been pressed)
• app_exit_events: can be used to send an AppExit event to exit the game
• menu_state(next): lets us change the menu state for the next frame
• game_state(next): lets us change the game state for the next frame
