change project_diva_2nd implication: project_diva -> project_diva_(series)
change project_diva_extend implication: project_diva -> project_diva_(series)
create implication: project_diva_f -> project_diva_(series)
create implication: project_diva_f_2nd -> project_diva_(series)
I'm currently in the process of separating the project_diva tag from images that don't have outfits that originate from the original Project Diva game. However, I can't do so to the project_diva_2nd and project_diva_extend tags since they currently implicate project_diva.
