Springs

Adds the Spring, a material with interesting properties. It can stretch and compress a huge amount before breaking, passes wind and projectiles, and can be built very long. Useful if you want a part of your Fort to have some bounce to it! Also handy vs modded weapons with high impact force; you can use supports made from them and not worry about them failing if you take a big hit. However, do not replace heavily stressed / flashing struts with springs. While they will not fail they are more easily stretched / compressed than other materials, so the weight will be passed onto the other surrounding struts as if you just deleted the strut; this could cause failure and collapsing. Copying any part of this mod's code is allowed, but please don't use the images as they took effort.
