Subject: [PATCH] Add damage-dealing random events to events.json (#104).

- array_burnout: damages solar_array (minDay 18, weight 1, requiresBuilding solar_array)
- systems_fault: damageRandomBuilt with morale -4 (minDay 15, weight 1)
- survival_45.json: add periodic repair every 3 days so damage events are recovered
- Two new damage tests: TestDamageEvent_SolarArrayDamagedViaApplyEventByID,
  TestDamageEvent_RandomBuilt_DamagesBuiltFacility
