Deadlier Nukes 2016-10-05

This is a simple mod that I re-created from one of my experiments at the request of Cadbro. I modified the GlobalDefines.xml, CIV4UnitInfos.xml, and CIV4ImprovementInfos.xml files make ICBMs and Tactical Nukes cost slightly more, but kill more pop in a city, do more damage to units, and destroy more buildings. It also makes most of the tile improvements more prone to damage (both nuke and airplane). ICBMs are no longer nukeimmune (I wanted to give a chance of the nuke detonating where it rests, but didn't know how). Enjoy.
