* Updated to ZDoom 4150:
- Fixed: PCD_MORPHACTOR and P_MorphMonster() needed NULL pointer checks.
- Make the DOOM 3 BFG Edition the last Steam path checked, so it won't override the regular doom.wad.
- Allow negative parameters to A_Light.
- Added IF_NOSCREENFLASH.
- Added NOTRAIL flag for PowerSpeed.
- Added NoRandomPlayerclass flag for MAPINFO.
- Added time display for alt hud.
- Added Brazilian Portuguese translation.
- Fixed: APowerSpeed::Serialize needs to call the super method.
