New Inactivity Metric

Current inactivity system is you just have to log in, do nothing and leave once every 5 days.

One system is to see if stockpiles accumulate. Say if stockpiles accumulate a greater amount than two days production. You would at least have to at least build or give it away.

Another is to require micromanagement. Teritories revolt. They would need to be attacked quickly. A province next to a revolted province has a higher chance of revolting. A coalition member can fight revolts if player is absent. You can join a game and select a country that is being played and take control of the revolted forces.
