1. Always use applyAgeImplant instead of setting ageImplant and visualAge independently

2. Replace PCAgeImplantAdjust widgets with just calling applyAgeImplant and applyAgeImplantOlder on the PC object
3. Switch applyAgeImplant over to a smooth curve instead of a stepwise function, so you don't get twice as much benefit from waiting 'til your slave is exactly 36 instead of 35 to facelift her
4. Remove old (no longer used) GenSkinTone widget
