Planned Ability to view all missed Bible Readings + Update

The Bible Reading Schedules are not released yet, but I wanted to save this idea for future development.

At the moment you can see your scheduled readings for today, and can manually move back or forward between to see previous or future readings. So you can change date to go back in time and view skipped or missed readings.

The idea is to be able to view all missed readings with a single click and to then optionally read them to catch up, or mark them as "read" or "skipped" en masse.

This will also contribute towards the future concept of a progress bar to show how far we are through a schedule.
