Forget treachery sooner

Limits the time you are considered treacherous for acting contrary to a former treaty to 5 turns after it has been dissolved for all types of diplomatic action. I always found it unnecessary to wait these turns out just because the game sets a limit. It's kind of a cheat so don't exploit it by backstabbing other factions too much.
And it might help with some of the "broken" gameplay mechanics, where the player gets a diplomatic penalty for saying yes to a peace treaty where the war was declared in startpos.
Load on top. Nothing changed in 1.3, so it's still compatible.
