Patch to work with opensim trunk ca. 2009/12/03.

 * prebuild patch updated
 
 * Biggest change: Physics engines now use Vector3 instead of
   PhysicsVector.  This was more than a search and replace, because
   Vector3 has a Multiply(Vector3, float) method, but *not* a
   Multiply(float, Vector3)... PhysicsVector had both.  So I had to
   rearrange some products.  Additionally, Vector3 is a struct whereas
   PhysicsVector was a class; it turns out that when you pass a struct
   in C#, it is passed by *value*, but a class is passed by
   *reference*.  (I'm sure somebody thought that was a good idea.)  So,
   a couple of functions (periodicBCs and one that moves characters
   around) had to be updated to deal with this.

I've connected this to a grid for the first time, and am not sure that
the boundary conditions are functioning quite as desired.  I will
continue to futz with it.

Commented out the mass and position/velocity rescaling, as that was
causing problems (race conditions that would mess up initial conditions,
and sometimes shoot stars way the heck out to the edge of the sim).
Added comments, some commented-out logging.  It now works for N=2.

(testing)

* Did some reformatting (removing more tabs, replacing them with spaces,
  as that's the Morally Correct way, and also matches the OpenSim coding
  standards).

* Added a bit of logging.

* Added AddForce to NewtonPrim, so I could use llApplyImpulse in a
  script to set initial conditions (or otherwise kick stuff around)

* Added a call to PhysicsActor.ReqeustPhysicsterseUpdate() in
  NewtonScene.Simulate().  Without that, the positions of the prims were
  not getting updated to the viewer-- the physics positions were being
  calculated and lost.  As of Opensim-0.6.6, micasim works again.  (I've
  only tested it with n=2.)

Added "using OpenMetaverse;" at the top of NewtonScene.cs, as it's now
needed for Quarternion.

Also, replaced all tabs with 4 spaces so that indentation would be
consistent regardless of whatever tab settings people have.  (Insert
rant about use of tabs in ASCII documents.)
