New guns hit effects

After playing Wings over Vietnam for a while i found original plane/object hit fx rather unrealistic.

Since i love both PAW and KAW mods i started working on something more resembling WWII guncamera footages.

In this pack are remade *objecthiteffect.ini for most guntypes as per bulletobject.ini descriptions.

So for lmg, hmg, 20mm, 23mm, 30mm and 37mm there are 6 new distinctive types of effects.
