Avoid rebuilds when unimportant morphology contents change
This changes the cache key generation so that it will ignore unimportant
fields of the morphology, e.g. description, build-depends, chunks.
description is unimportant because it does not affect building, and
build-depends/chunks are unimportant because they are already considered
