Another Balance Change (#987)

## Description:
Reduces attack speed for large attacks. A further 10% increase in
attacker losses. minor 5% decrease in pop growth. Attacks against Terra
Nullius fade away as in v22.

This addresses the community poll finding that many players consider
current troop movements to be too fast. The latter two changes help nerf
attacking and slowdown snowballing.
