I made it so the command no longer requires the "Target type" to be provided,

it now recognizes whether the target is a directory or an archive on its own.

I added in a help message, which is still incomplete, but should make it easier
for admins to know how to use this new command. I believe we should also provi-
-de an example of the location.csv and metadata.csv files, so there is no conf-
-usion. Also, I made it possible for the command to recognize zip files as a
valid archive. I also made some minor changes to the commands description w/i
the larger gmg command help menu.
