Minor refactorings to PadSlot now it is pretty much done
Remove unneeded constructor (will fix generic definitions if needed later)
Avoid getting stuck in "continually" (and be generally safer); no need to map KitV_ to a sequence of PadV_, it already is one
Well, no point keeping the comments as it seems to be working
A safer (more functional) way to decide what to do based on V3 vs V4 dump type
Tiny refactorings
