Enhancement for #224

I made a small enhancement to the fix for issue #224 which was still open

Changes made:
- fixed typo in "totalDownload"
- if only one package is display render "You have one package." in the table footer
- if more then one "You have a total of {0} packages."
- if the user has only unlisted packages the listed table will now not be rendered. Instead it just shows "You don't have any packages here."
