Members - IAF Weapon Drop mod for Alien Swarm

Almost all weapons were modified more or less noticeable. Some of them are big changes (like semi-auto Railguns and Sniper Rifles or Miniguns with lot more ammo but much longer reload time) and some are only damage or reload time tweak. Also removed class restrictions. At beginning of this mod it was a 200 MB standalone modification, but the more I worked on it, I finally decided to take what is most essential into VPK file, that is easier to install/uninstall and most important and it's now only 1.59 MB unpacked (99% less than first version!).
