Implemented D-AA acid mutations. Added H-bond files to the repository.
Modified the changeResidueType function to use the previous backbone
atoms. ComputeEnergyMol now calculates eref and entropy if they are
turned on. Astar search no longer recalculates energy when doing a rigid
search.
Added bin directory to .gitignore
