M249 World model fix

Apparently when swapping out the player model of the M249 with the new one (Schmungs), they forgot to replace the world model.

I downloaded Schmungs model and recompiled it for the world model so now the player model and world model match up. Also, if you have a personal texture for the world model of your M249 then it will not get applied to this one, as I made this one use the view models textures.

Enjoy :)
