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.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

## Please put your Discord username so you can be contacted if a bug or
regression is found:
