* Reconstructed a list of all PACKETVER types, by reverse-engineering it from places in the code where the define is used

- recovered PACKETVER 6 which was added in r51, but overwritten by r141, one of the dumbest commits that I have seen so far
- since 6 was the 'new trade window' update, it and its corresponding reply packet will now be used from now on instead the old version
