Consider solution for long particlesystem runs

Modify the Snowing example particle system with: "startTime: 1000 * 60 * 60 * 24 * 10", which fast-forwards it to situation at 10 days. Notice how particles animations are not smooth. Seems that currently ~6 days is the max time you can run the particlesystem until float times don't have enough accuracy to smooth deltas.

This is a rare case, but consider ways to handle this. Would particlesystem automatically reset to start after some max time?
