[Rock-dev] Automatic invalidation of the RigidBodyState

[Matthias Goldhoorn]

I stumble VERY often (and just again) over code that simply uses the RBS 
but does not call invalidate() on it.
An check if some values are invalid are useless if no one set's this.

I write components that does these checks, but if i depend on some 
(beginners)
code that does not do the invalidation correctly i get into strange and 
not easy to debug errors. (because i though i catched already 
uninitialized values).

Because of this (even if i know we can trigger some bugs with this 
change), i would really like to introduce an constructor on the rbs 
which does this initialization if no one screams... opinions?
