Created reference implementation of DIIS for converging AMOEBA dipoles.  Also some minor code cleanup.

Plugins work with CPU platform.  This involved separating the reference implementations of plugins into their own libraries.

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

Platform specific header files get installed.  This allows plugins to be built with just an OpenMM installation, not a full source tree.

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
