AmoebaMultipoleForce did not report particle groups, which could potentially lead to incorrect reordering

Converted the array containing atom block indices for the neighbor list from ushort2 to int.  This removes the hard limit of 2 million atoms.

Fixed units for AMOEBA dipole and quadrupole moment (now returns Debye and Debye * Angstrom, not Debye/10 and Debye*Angstrom/100.)  Rationale is that Debye/10 is not a common physical unit.  Note that CUDA platform still gets quadrupole to be incorrect.

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

When converting to fixed point, multiply by 0x100000000 instead of 0xFFFFFFFF.  This should be (very very slightly) more accurate, since its reciprocal can be exactly represented in floating point.

Fixed test failures caused by linking to the same library twice, once statically and once dynamically

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.
