Subject: Step counter: reset every 24 hours, and load offsets from the log
 file when initialising. - This is quite crude - Firstly, we assume that the
 last record in the file is chronologically the last. This needs more
 consideration. - we do check if we're on a fresh boot, but we just give up
 completely if it's not a fresh boot, which may work, but needs testing to
 figure out how it actually works in practice
