Add MD5-based integrity checks for the snapshot archives maintained by the build master. If an archive is corrupted (for example by interruption of the archive creation), the build master will detect this because the MD5 checksum file is either missing, or does not match. Closes #56. Thanks to Chandler Carruth for the suggestion!
