Percentage chance Historical Rivals / Friends expire when accepting Institutions

[psbirch]

What it says on the tin: As our games verge from history over time, so too should some of the baked in modifiers. I propose a cumulative 5% chance of any of a county's 'Historical Rivals / Friends' modifiers expire when that country adopts an Institution.

For example, when accepting Colonialism France would have a 10% chance of removing the "Historical Enemy" modifier with Austria.

That sounds like a pretty arbitrary thing to pick as the trigger for it. There is already the possibility to lose a historical friendship by fighting your "friend".

If there are to be ways to lose historical rivalry, or more ways to lose historical friendship, they should similarly have something to do with the interactions of the countries in question.
