Fixed a bug that would cause the tab for a day without canteen offers to not be shown, causing the offers for the next days to be shifted over, thus not showing the offers for the last day that's available online. I know I didn't explain that very well, but it's fixed now anyway, soo (: also made some minor visual adjustments to margins and colours
