ZZArchiveEntry archiveEntryWithDirectoryName: Does Not Create Valid Entry

[levigroker]

Hello,

If I create a directory entry using [ZZArchiveEntry archiveEntryWithDirectoryName:name] where name does not end with a \ (slash) the resulting archive is invalid and attempting to decompress results in an error:

checkdir error: <directory name> exists but is not directory

It would seem archiveEntryWithDirectoryName: should sanitize the given name to include a trailing slash if that is indeed required for the archive to be valid.
