[vos-d] parameterized views

[Mats]

For many cases it doesn't matter if animations are not synchronized.  
It's still important
to have that option though. If a world for example has a boxing ring,  
it would be
important to keep the avatar animations synchronized while inside the  
ring, the time of the animations that is, so the server can determine  
who punched first etc.
