Harpoon 3 Patch

After releasing 3.5.1, I was informed that it didn't fix the "Nuke me and I'm immortal" bug for all cases. So, I took a much closer look at this area of the code and discovered 2 major bugs (and also made a minor change in the same area).

• Due to the way the Area Effect Weapon code was originally written, many types of Facilities could never be damaged by ANY Area Effect weapons. The technical problems had to do with switch statements not being able to guess at which part of a bit field to test. This has been replaced by a series of if-else-if clauses.
• The Facility::ApplyDamage function was also broken badly. It only worked well when the damage being applied was small (anything larger than 127 was always broken, and numbers above 116 could also be broken in certain situations).
• The minor change was to let Runways be damaged by large attacks. Previously, they could never be destroyed (or even damaged). The worst that could happen was that they would have "Runway Criticals" applied against them, which "shortened" them for a little while. Now, given enough big weapons, you can slowly destroy a Runway to the point that it eventually dissappears (or, just hit it directly with a Nuke, and it goes away fast).
