Allow Nuke_Proof effect to depend on diplomatic relationship between
unit and city owner (and also on properties of the specific tile it
attacks). Remove the hardcoded behaviour that it doesn't affect
allies/teammates/self.

In all supplied rulesets, use this ability to change the rules so that
SDI Defense now works against allies.

See gna patch #6693.
