Hard quitout on full stash leads to rollbacks in single player

[andrewdudzik]

A full stash error leads to terminating the D2R task. In single player, saves are infrequent and a soft quitout is needed to avoid lost progress.

I experienced the following scenario: Botty finds nice loot, Botty goes to put loot in stash, stash is full, Botty kills D2R, loot is gone forever. Intended behavior is, I suspect, to keep the loot in inventory.
