0.9.1 – poll less, or only in certain hours

Poll less, or only in certain hours – thanks @Michael.0000.

Added

• BRIDGE_POLL_SECONDS – seconds between the polls of run (default 60, upload mode 600;
  --poll-seconds still wins). BRIDGE_POLL_SECONDS=300 polls every five minutes.
• BRIDGE_POLL_HOURS – poll only in these hours: 10-18, several ranges like 6-9,16-22,
  or over midnight like 22-6. Outside them run skips its polls and watch does nothing;
  the half-hourly full runs go on, so an activity recorded outside the window still arrives
  (within about two hours instead of a minute) and so does last night's wellness.

The real end of polling would be a webhook from Intervals – see the
feature request.
