(FrictionForce) too keep things from getting too wild.
Fix ARL: Springs should be evaluated after SlipForces. But we can't do that because currently we are velocity based and need to be evaluated before the LocatorForce -- otherwise we'll never affect the particles' locations until the next tick. SlipForces need to be evaluated after the LocatorForce because their main purpose is to fix the "mistakes" that the locator force makes (thus keeping the particle positions correctly relative to each other).
Solution: Make a spring force that replaces the locator force, and correctly takes occilation into account based on the current velocity.
Property group 'SpringForce'
Default value: 64.0
Spring constant. (Larger values == stiffer spring)
Default value: 0.333333
