Implement some sort of backoff from downloading journals, if the player is not active

[itssimple]

Currently we pull every 10 minutes, for all commanders.

Maybe we should implement some kind of backoff, if the player isn't that active.

If the player has been active during the day, we pull every ten minutes
If the player has not been active today, but yesterday, we pull every 30 minutes
If the player has not been active yesterday, we pull every 3 hours
If the player has not been active the last week, we pull once every 12 hours
If the player has not been active outside of the above ranges, we only pull once per day.
