Indrajit Raychaudhuri 54dff31b63 archive: Enhance 'archive' helper to support multi file archive
We now allow multiple paths (files/directories) to be archived in
one shot. Validation of the target path(s) is now delegated to the
actual archive helper.

Where 'archive.zip' uses any of the following extensions:
.tar.gz, .tar.bz2, .tar.xz, .tar.lzma, .tar, .zip, .rar, .7z
There is no '-v' switch; all operations are verbose.
