Model Tactical Bizon instead of p90

In my opinion, a decent replacement for the standard p90 for css.
As you can see in the video Tactical Bizonhas a good rendering and looks pretty impressive.
The sound of shooting is like a standard m4a1 with a silencer, the sound of reloading is like a standard p90.
Operation has been tested on all versions of counter strike source.
Available VGUI and world model.
