* Updated to ZDoom r3504:

- Fixed: FileReader's FilePos is relative to the start of the file, not relative to the start of the lump, so r3496's change to FileReader::Gets() was only valid for lumps at the start of a wad. (This function was still incorrect before that, though, since it made FilePos relative to StartPos after it had been used once.)
- Do the P_SightCheck() last in A_JumpIfInTargetLOS, since it's the most expensive check.
- Fixed: A_JumpIfInTargetLOS did the FOV cone check from self -> target rather than from target -> self.
- Fixed: Reset to the PlayerPawn's default render style and alpha in G_PlayerFinishLevel().
- Fixed: M_CreateMenus() is too soon to call UpdateJoystickMenu(). It needs to happen after I_InitInput(), which happens during V_Init2().
- Apply patch to prevent the flash state from being processed twice after using A_GunFlash.
- Fixed: Disable absolute wall lighting when in the shadow of a 3D floor.
- Fixed: Trying to -playdemo a demo recorded from -loadgame would crash if you did not -loadgame the corresponding save.
