Integrators control when atom reordering gets done, instead of having it happen automatically when forces are evaluated.  This simplifies some code, and also improves unintuitive behavior with CustomIntegrator.

Long range correction for both NonbondedForce and CustomNonbondedForce takes the switching function into account

Fixes a hard to catch bug when a boundingBoxSize increases in size in between a timestep, but does not trigger a rebuild of the neighbourlist. Affects the usage of singlePeriodicCopy in nonbonded force.  

When computing kinetic energy, make sure the shifted velocities are perpendicular to the constraints

Reduced memory use for random numbers, eliminated unnecessary calculation when generating random numbers
