update meta (#1397)

## Description:

* cap trade ships at 100, instead have more ports increase gold per ship
* nerf defense post speed reduction. Sometimes attacks were so slow the
attacker could "store" troops in the attack.
* adjust trade ship spawn rate: increase spawn rate early game to speed
up game play
* nerf MIRVs by making blast radius smaller. This allows the territory
to stay continuous, allowing the attacker to conquer faster and speeding
up late game.
