Incoming nuke event filter (#2092)

## Description:

I have found most attack information to not be very useful, particularly
during the late game when MIRVs are flying and cities and ports are
being gained/lost by the hundreds.

However, even in these circumstances I would still like to see incoming
nuke messages.

Attacks filtered out, incoming atom bomb message still appears:

/>

## 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
- [ ] I have added relevant tests to the test directory
- [ ] 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:
