[Enhancement] New Tracker of Necessity Items and Price

Another new add category to further enhance information, I will be adding different common items, especially necessity items like Bread, Rice, Egg, etc at the side column [right side] of my webpage. This is to track the overall costs of these necessity items and how we can better manage our finances. The whole world is facing higher cost of living and this is why Singapore is affected too. If we are not careful, our saving will be depleted and "Game Over". Basically from 2018 till date, we subconsciously realised that things and groceries were increasing year by year, ending up us paying for lesser things with the same value. Stay tuned and I will slowly be working to populate the data.
