to allow Ant generated zip/jar/war/ear files to be extracted on Unix
boxes without permission problems for directories.

This one uses external file attributes like InfoZip's zip does, this
is a rough cut - the infrastructure to set arbitrary permissions and
add user/group IDs via Zip's external fields is there, but not used
ATM.  Directories will always get 755 permissions right now.

The testcases work on my box, and I can extract Ant created archives
without any trouble - can't await tomorrows Gump run.

package documentation for org.apache.tools.zip will follow.
