Create: Iron Vaults

1.1.1

Fixes

• Crashed at startup when Design n' Decor was not installed (NoClassDefFoundError: dev/lopyluna/dndecor/.../DyedContainerBlock during mod construction). The container registration was skipped when the mod was absent, but the JVM verifies a whole class before running any of it, and the code that would have created the container blocks was enough to make it resolve Design n' Decor's classes. The Item Silo registration had the same latent problem with Create: Connected. Both are now isolated in classes that are only loaded once the mod they depend on is confirmed present.
