The clown is gone! 🤡 Nations send much better emojis now (#2696)

## Description:

Previously, nations just spammed these two rather toxic emojis: 🤡😡

They now send fewer emojis while attacking, and the clown emoji is
reserved for special cases.

They got the ability to send emojis in much more cases:
- Human didn't donate enough for relation update
- Human did donate an ok amount
- Human did donate a lot
- Responding to emojis that they get sent from a human
- Nuke sent
- MIRV sent
- Retaliation warship sent
- Traitor tries to ally
- Threat asks for / accepts an alliance request
- Disliked human tries to ally
- Friendly human tries to ally
- They are getting attacked by very much troops
- They are getting attacked by very little troops
- Congratulating the winner
- Bragging with their crown
- Charming their allies
- Clown-Emoting traitors
- Easteregg: Sending a rat emoji to very small humans

## 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

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