RFX: Declaring friendship

[Infixo]

From Wiki:
There is currently a bug where a player can renew friendship with an AI indefinitely no matter how many negative relationships they have by renewing friendship as soon as it ends.

Edit. This may be related to the fact that Diplo score is updated only once per turn, probably at the start of the turn. So, after the friendship expires, it is still high reflecting the Friend diplo as if it'd been still active.

Possible solution: add a GamePlay Script that would manually tweak DiploScore to reflect the current value. Attach to Events that might change it during the turn.
