Title: #6177: Fix for 6030 upgrade rules

Updated UpgradeRules to correct regressions caused in yaml.
* Fixed the incorrect double entry size for HealthPercentage and PerCell warheads.
* Fixed ValidTargets and InvalidTargets not being propagated from Weapon to Warheads. (Causing most weapons to damage passing airplanes and such nonsense).
