Make Sweet Tooth a starting trait (CleverRaven#33477)

* Changed Sweet Tooth to be a starting trait

* Added Sweet Tooth starting trait to NPCs

Removed ANTIJUNK from possible starting traits, created a new trait group with both PROJUNK and ANTIJUNK and added that group to possible starting traits. Possibility 5 because of allergy.
