ARGG/Garrys mod Physics Gun implementation

To implement the ARGG physics gun to your half-life 2 mod its actually very simple here is what you need to do:

If your mod is based on Portal use this version of the physics gun
If your mod is based on Half-Life: Source use this version of the physics gun
If your mod is based on Half-Life 2 use

Finally add the physics gun to vpc and rebuild your project you should now have a rotational physics gun

(make sure to have weapon_physgun.txt)
