v0.32.0 Replenish and combat points

This feature has been brewing in my head for a while. "How to replenish health points over time".
I decided on a periodical function, and only for players for now. It will add one point every 10 seconds. (Is this too often?).
I also added another idea, "combat points", which is rather stamina. It will decrease when attacking, and replenish over time. If it's 0 you can't attack, and it will hurt your defense.
I needed to get this sorted out to before the next bigger thing that has been missing from the framework.
