Cache FA_Elec data that are loaded repeatedly with beta_nov15
With the beta_nov15 scorefunction, certain FA_ElecEnergy data are loaded from disk every time the term is instantiated or cloned. This is a HUGE problem in protocols that copy scorefunctions in loops -- especially when they're being run on Blue Gene. This pull request aims to allow these data to be read once per process and cached as global (static) data.
