Long term history browsable by day

It would be useful to browse empire and family news feeds by RL day, so you can evaluate what’s happened within a given 24 hour window.

All history should also be permanently accessible throughout the round, so you could see long term day-by-day progress as well to allow all of your history to be a factor in making plans.

This should be based on UTC so all family members have a common reference point for news items.
