Remove imports of the soc.logic.key_name module, since it was deleted by r1071 (and wasn't referenced in these modules anyway). Patch by: Todd Larsen

Replace nick_name and its variants with public_name. Remove the soc/templates/soc/person/edit.html template, since it does not appear to be referenced anywhere (and contained a nick_name reference that would otherwise need to be remedied). Patch by: Todd Larsen
