Damien Elmes 32fde2a072 encode daily steps in left
When a user has learning steps that extend past the daily cutoff, we end up
counting them all instead of only the ones that would be done today. In order
to avoid this without expensive calculations or db schema changes, we
calculate the number of steps until the daily cutoff and pack it into the left
column, as totalLeft + leftToday*1000.
