D-Minder

- Fixed: sun sessions could be refused when your vitamin D rate was small (low sun, clouds or darker skin). Small rates are now counted exactly instead of rounded down.
- Fixed: removing a duplicate supplement dose could mark that day as skipped.
- Progress dials: being on plan now points straight up; the needle only pins at twice your plan.
- Home: tomorrow's sun arc fits its card, and the next opportunity says how long until it starts.
