The ability to install unaudited extensions directly from a zip file
can be useful for testing and code review, so implement a corresponding
command that complements the previously added 'pack' command.

Extensions are uploaded to extensions.gnome.org as zip files that
not only contain the extension sources, but also compiled GSettings
schemas and message catalogues. To make this more convenient, add
a corresponding command for creating an archive suitable for up-
loading.

We already support displaying extension details for the list command,
so it's a logical extension to also support showing extension info
for a particular extension (not least because the shell has a
corresponding D-Bus method).
