Created a faceblend test scene with Patrick on cart and face change script (press F/G)

Currently the happy/angry face poses can be triggered by holding F or G. Next I want
to add more functions to the script so pose changes can be called from other scripts,
something like: if(goodShot()) SendMessage("SetFacePose", "Happy"); or so
