o Added C12 shift term, to match GMX.
o Added tests to compare energies and forces directly to GMX, with and without exclusions.
o Modified set/get LJPME parameters to look similar to electrostatic equivalents.

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

All platforms now handle nonbonded exceptions in a consistent way (they ignore cutoffs and periodic boundary conditions).  Also started OpenCL implementation of CustomHbondForce.

Use a consistent (and more accurate) value for electric constant everywhere.  Also cleaned up handling of constants and units in various places.

Modified the API for lots of classes so that the number of particles/bonds/etc. need not be specified in the constructor.

Changed how kernels get initialized.  StandardMMForceField now has you set the 1-4 interactions explicitly.  CMMotionRemover allows the removal frequency to be set.
