Created a public verison of the applyRotationMatrix function so that it can be accessed from outside

stretch-bend test correctly.

The potential energy calculation done in the ReferenceStretchBendTest file was
updated to mirror that of the Reference kernel, but first I made sure that the
test passed *before* updating to the new energy expression, just to make sure
that the energies and forces didn't *change* with the new expression.

of just 1.  Backwards compatibility is provided by making the 2nd force constant
default to -1, which is reinterpreted as "copy the first force constant".

Updates both the reference and CUDA kernels.

Modified the AmoebaMultipoleForce.getSystemMultipoleMoments method with two extra arguments; toggle whether to evaluate energy/force and select maximum multipole order.

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

added tests to TestCudaAmoebaVdwForce for dispersion correction using box of 216 water molecules
AmoebaVdwForce and AmoebaMultipoleForce now throw execptions if cutoff > 0.5*(box size)

Added AmoebaMultipoleForce::getSystemMultipoleMoments() to get system multipole moments; based on TINKER subroutine moments()

TorsionTorsion grids reordered, if needed, so that first angle is the 'slow' index
