#15 directories entries not recognized by windows

[Anonymous]

entries created for directories are not recognized correctly by Windows. The following output from zipinfo -v shows the difference between a zip directory entry created by rubyzip and one created by zipinfo zip.

rubyzip should store directory entries instead of deflating them and rubyzip should set the MSDOS attribute to dir, as zip-info zip does.
