Variable Timestep adds energy to particle system #86

See stackoverflow here:

Changing timestep causes particle system to gain energy and become unstable. Box2D bodies remain unaffected by the timestep changes. LiquidFun's particles should behave in the same manner (with respect to the timestep) as Box2D bodies.

Found the same problem when building for javascript / browser and targeting vsync. Particle bodies almost come to a rest and then appear to bounce/oscillate (all in sync).

Sad to see that this project is probably dead...
