Real space Ewald (direct summation) is now in kCalculateCDLJForces.h, reciprocal summation is done in a separate kernel

Implemented the Ewald summation method in the reference platform. Preliminary cuda prototype is included.

Implemented setting random seed for reference platform, as well as adding it as an option to BrownianIntegrator and AndersenThermostat.

Checked in explicit solvent implementation for Cuda platform (cutoffs, periodic boundary conditions, SETTLE)

Made setting of RNG seed consistent w/ logic used for Cuda 

Minor edits; force duplicationFactor to 1 if no. particles < 65; for system w/ 32 atoms, NAN were appearing in nonbonded force term; plan to fix later

Added more ik,jl gathers for bonded forces
Redid shared #define setting in CMakeList.txt

because virgin computers without CUDA generate loads of errors trying
to find CUDA on cmake run.
