- Fixed: Killing a morphed monster must trigger A_BossDeath on its unmorphed self.
- fixed: CHANGELEVEL_RESETINVENTORY may not change the player's health.

APlayerPawn::GiveDefaultInventory altered the player_t's health value which was ok as long as this function was only called from G_PlayerReborn. For all other cases this initialization was wrong and G_PlayerReborn should do this itself.
- added a compatibility option for stopping sounds when the owning actor is destroyed.
