Simple fix to combining rules allowing AMOEBA VdW parameters to be zero.  Zero parameter excludes all interactions involving that particle, in agreement with TINKER.

Commented out some minor optimizations in AMOEBA that were making the forces incorrect.  AMOEBA energies and forces now agree with TINKER to within 1e-9 (fractional energy) 1e-5 (fractional RMS force error) for NPT simulations on rectangular water boxes with PME and direct or mutual polarizability.

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

Began implementing new mixed precision model that does integration in double precision and force evaluation in single precision

Modified Reference platform of AmoebaVdwForce to handle PBC, cutoffs, tapering and dispersion correction
