-The selection menu shows up when itemweak mode is selected.
-The selection should save for each belly along with other prefs.

->All, contains the whole list as before apart from possible specific ones. Is the designated default option.
->Acrid, contains flavors implying regular nasty digestion.
->Dirty, contains flavors related to visual contamination.
->Musky, contains suggestively sloppy flavors without excess filth.
->Smelly, contains more airborne flavors without visual slop or crud.
->Wet, contains flavors of more neutral-ish soakage.
