[Papervision3D] papervision & augmented reality

[Alexander Wichers]

I managed to get stuff working, here is my demo:
http://mammoth-project.org/dl/ar_demo.wmv

My server now spits out papervision compatible projection and object 
matrixes, it took me more than two days to get to this result. And it's 
definitely not 100% (x,y,z position is of when rotating), but it's 
close, looks cool and good enough for now..
