Separated hardware query functions into a separate file.  CPU platform checks for the correct hardware.

Created API and reference implementation of restricting CustomNonbondedForce to selected interaction groups

Converted the routine for identifying molecules from a recursion to a loop.  This avoids stack overflows with very long linear molecules.

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

Using a const Vec3& instead of three doubles for the AnisotropicBarostat API.  Still figuring out SWIG issues.

Long range correction for both NonbondedForce and CustomNonbondedForce takes the switching function into account
