Bug Description:
RFE: Add ability to set File Attributes on Zip Entries

Inside ZipOutputStream there is already a note: 'REMIND: add support for file attributes'
so it looks like there are already plans to do this

The writeCEN method already contains the line writeInt(0); // external file attributes (unused)
All we need are method to set/get the File Attributes on a Zip Entry and for this
writeInt to be changed to write that value instead of 0.

I suggest adding methods allowing for any int value, and possibly later on adding
additional convenience methods to set the file attributes for known platforms as
documented in http://www.pkware.com/documents/casestudies/APPNOTE.TXT)
