implement duos (#630)

Implement Duos team mode.
Also assign teams to nations at the start instead of assigning them
randomly on spawn. This gives more consistent team sizes

- [x] I have added screenshots for all UI updates
- [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
regression is found:
