A registered person creates their own tags for a package

[johnbywater]

Notes

• Should provide a text box where users can add space separated tags (a la delicious).
• if though tags are only associated tag creation should be seemless (so if a tag does not already tag exists it should automatically be created in the background)
• would like to provide a list of relevant existing tags. For time being could just list all existing tags below entry box but in long run would like auto-updating/auto-suggesting listing a la delicious
