Print results as table (if possible without extra modules)

[vmavromatis]

It would be nice to print the results nicely in a table-like style with these 4 columns: Package, Status, Description, Libre Alternative

I'm trying to keep this module-free, so bonus points for not using modules!

If we're going to print out everything as a table, it would be nice to be able to sort the results by column using command-line flags. -s for sorting by status, --name for sorting by name, etc.

Might be worth a separate issue.
