Fix players not being able to pickup items due to default values.

The old flag for picking up loot was default to false, making existing players not able to pickup items. We now use this flag for Players, which gives us the problem we had in 48b46f83.

To fix this, we add an incremental flag that will be cross-examined to check if the data was saved before or after the flag level was introduced.
