- fixed: A_Warp didn't initialize oldx/y/z in all situations.
- added HARMFRIENDS flag.
- fixed: damage of amount TELEFRAG_DAMAGE should not be reduced by armors absorbing some damage, it'd lose its magic-ness, that is needed to ensure a guaranteed kill. The same applies to autousing health items.
- fixed: G_FinishTravel must synchronize the CF_FLY flag with MF2_FLY.
- fixed: Strife's peasants couldn't harm the player because they were defined as friendly.
- fixed: A_Respawn did not restore the flags6 and flags7 fields.
