Mandatory Friend Reporting

Concise description:
Specifics/Details:
How this will benefit the site and/or other comments:
- When you join a game with friends, the game log will update to say "Kiron" and "xiangwang" are friends
- [optional]: The friends list will be updated automatically when you play a certain number of games together or if you ever log in from the same IP
- [Optional]: It could even indicate this on the game finder
Specifics/Details:
- It will make "secret diplomacy" accusations easier to disentangle from just wanting your friends to succeed
How this will benefit the site and/or other comments:
- No more Kiron/xiangwang debacle
- It will save me having to file 500+ C+A reports for people who play with their friends
- Because of the game log updater, people will play with their friends less perhaps
