Though we were aware that people took advantage of a long standing bug pertaining to keep inventory, for administrative usage, this is now fixed and due to the request of undoing this, I have decided to create a permission node to make this a feature instead so that those who don't want to deop themselves can make both parties happy.

Players will now be required to have the graves.keepinventory.bypass permission in order to get the old behavior back, which is false by default.
