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

Continuing to implement new CUDA platform: HarmonicAngleForce, PeriodicTorsionForce, RBTorsionForce, CMAPTorsionForce

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

Continuing to implement ReferencePlatform (implemented kinetic energy calculation and LangevinIntegrator)

Created a test case for StandardMMForceFieldImpl's findExclusions() method.  Fixed some bugs that it found.  Created a CMake script and configured it for building and running test cases.
