* Made physical prim stable enough for the general population to turn on. (though I still don't recommend it for welcome regions unless object build is off.

* Updated the ode.dll for windows with a more reasonable stack space reserve.  Linux users will need to type ulimit -s 262144 before starting up OpenSimulator if using Physical Prim to protect against stack collisions. or run the included ./bin/opensim-ode.sh to start up OpenSimulator in ODE mode.
* Added internal collision score and am keeping track of 'high usage' prim.
* Tweaked collisions some more
* Tested up to 460 physical prim in extremely close quarters (which was previously impossible in OpenSim).  After 460 in tight quarters, physics slows down enough to make it hard to do any moving, however..  non physics things still work, such as logging on to the simulator, etc.
