Add importtables roundup-admin command.

I am surprised this doesn't exist. It's the dual of exporttables.
Output of exporttables can't be imported by import, so I am not sure
why it's useful. I can't find the sourceforge ticket that is
referenced in the creation of exporttables.

I considered trapping the error generated when import can't find file
content, but that's not a great idea as it can mask an
invalid/incorrect export and the loss of data associated with it.
