Partition all-cabal-hashes into case-insensitive-safe components.

Browse Source 
OS X by default has a case-insensitive filesystem, and fetching
all-cabal-hashes there fails due to a hash mismatch caused by package
pairs like compactable and Compactable. This partitions the package set
such that each partition contains no equivalent-up-to-case pairs.
