This is the last parameter for A_RadiusThrust() DECORATE function.
If it is omitted or none, then A_RadiusThrust will behave as usual.
If it is set for some species name, it witt thrust only that species.
Of course, these species should be +VULNERABLE to be thrustable.
* Added ViewAngle/Pitch/Roll properties to actors.
- These are offsets for camera angles that allow turning the camera without affecting aim or movement direction.
- Added A_SetView<Angle/Pitch/Roll>, which will set the view direction.
- Added ABSVIEWANGLES flag, used to make the view absolute instead of an offset.
* Converted functions to be direct-native.
