APP request: Drink counter

@Hank on top of Gordon's suggestion with the layout module I would have those suggestions:

• Replace your custom time handling with the locale module https://www.espruino.com/Bangle.js+Locale

  // Current time, e.g. 15:49
  require("locale").time(new Date(), 1);
  
  // First drink, e.g. 15:49
  require("locale").time(firstDrinkTime, 1);
  

• You have a bunch of assignments like

  a = a + 1;
  b = b - 1;
  

that can be shortened to

a++;
b--;
