[Power Manager] Round battery percentage

[RKBoss6]

I noticed that when monotonic percentage was selected, it displayed percentages with decimals, which was hard to read in most battery widgets, so I fixed it here.

Thanks!

I also have noticed that monotonic percentage is not truly monotonic, it fluctuates, instead of only going down when not charging, and up when charging.

I will see if I can fix it, but anyone else is welcome to take a look as well

if (settings.forceMonoPercentage){
    var p = Math.round((E.getBattery()+E.getBattery()+E.getBattery()+E.getBattery())/4);
    var op = E.getBattery;
    E.getBattery = function() {
      var current = Math.round((op()+op()+op()+op())/4);
      if (Bangle.isCharging() && current > p) p = current;
      if (!Bangle.isCharging() && current < p) p = current;
      return p;
    };
  }

Rounding the p value right away might be slightly cleaner logic.
