Sanitizing packets

[funjoker]

Some people might be afraid of their privacy and possible data abuse (which is reasonable). So i made this WIP to be able to sanitize data from packets and redump it. Sanitizing requires manually marking parts except guids. Guids are always sanitized by different seed.

Packets which are unhandled or erroring on parse are not dumped.

BattlePay stuff might need some further look, because we ignore these packets completely
