Automatically support all DamageClass

[JavidPack]

The mod could automatically support all damage class. There should also be a distinction or some way of identifying DamageClasses that inherit from other classes. There is also an issue of how to manage damage classes registered by mods vs the automatic ones, to avoid duplicates but still honor the submitted icon.

Right now I think the mod does CountsAsClass, which is fine. If we do it automatically, there are a few vanilla classes that would be unnecessary, so more thought or planning is required.
