[enhancement] Function to download entire directories as zip archives

[kush5683]

Would it be possible to add functionality to download directories as zip archives. As of now we have to zip the directory on the host and then run updog one level higher. It would be nice to run updog in a directory and be able to download all the contents of the given directory.
