Changing demos tickrate about bepuphysics2 HOT 1 OPEN

The demos simply execute updates at the refresh rate of the monitor or as close to that as it can get. That does indeed mean that changing the timestep duration from 1/60 to 1/120 will make time progress half as fast, since by default, only one timestep is executed per graphical frame.

This was done for simplicity and for debugging; it's often helpful to have a visual representation of every single frame, and there's no hard requirement for consistency in the demos application.

That said, it was definitely less wonky back when most monitors were only 60hz. I was playing around with it on a 240hz laptop recently and... something does probably need to change :P

I might just add a simple flag for temporal accumulation based timestepping. There's already an example implementation commented out in the demo update showing how to do it.
