Cloth simulation presets are gone, how do I get them back? I'm trying to use one of the cloth presets in the Simulations tab, but I've accidentally deleted a couple of the presets and I don't know how to get them back. I've tried restarting blender with a new file, but the cloth sim. still didn't have the Presets. And I even Tried to Load Factory Settings as proposed in this answer as well and it still wouldn't work! If anyone can tell me whats going on, that would be great. Thanks!
It's probably easier to just tell you what the default presets are:


Cotton: Steps 5, Mass 0.3, Structural 15, Bend 0.5, Spring 5
Denim: Steps 12, Mass 1, Structural 40, Bend 10, Spring 25
Leather: Steps 15, Mass 0.4, Structural 80, Bend 150, Spring 25
Rubber: Steps 7, Mass 3, Structural 15, Bend 25, Spring 25
Silk: Steps 5, Mass 0.15, Structure 5, Bend 0.05, Spring 0


These are as of 2.77.
