Allow emojis as category icon

Using emojis in the budget section looks really good and you had a really good idea implementing this. Why don't you allow it for categories as well? It'll be really cool and it'll expand immediately the app icon base. This will improve the aesthetic of the app and you won't have to worry anymore for providing or refreshing the in-app icons. Also it'll benefit both, Android and iOS versions at once.
