Using a const Vec3& instead of three doubles for the AnisotropicBarostat API.  Still figuring out SWIG issues.

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

OpenCLArray is no longer templatized and doesn't provide a host buffer.  This is in preparation for adding mixed/double precision support.

Variable time step integrators correctly report the size of the last step taken.  Also improved accuracy of integration unit tests.
