Dynamically show lunch items in simplified lunch module

[michaelgira23]

Right now, lunch categories are shown based on hardcoded css-element-queries CSS rules. This should be migrated to a method similar to the simplified-schedule component, where it detects each element's width/height, and shows the element if there's enough room. This would allow us to adapt to different screen sizes and lunch menus showing more categories if there's enough room and showing less if there's an abnormally long menu.
